Maps keeps crashing
After a recent update, gnome-maps keeps crashing randomly, most often after only a few moves of the map. Sometimes simply clicking on the map will trigger the crash. As things stand, the application is hardly usable. When running from a terminal, I am getting variations of this message:
***MEMORY-ERROR***: org.gnome.Maps[6666]: GSlice: assertion failed: sinfo->n_allocated > 0
While researching that error message, I found out that running G_SLICE=always-malloc gnome-maps somehow prevents it from crashing. I hope this is not too much of a dark spell, but it certainly looks like a shady workaround.
There is no MATE maps, nor MATE globe to try as a replacement, unfortunately, and reverting to the previous version does not help. There is KDE's Marble, but it is seems to be siphoning RAM like a thirsty vampire rabbit. It also crashed once, so I am currently using the dark magic trick instead.
After doing apt purge gnome-maps and installing the package again, Maps is not crashing any more.
apt autoremove
This is a typical example of why some deem it wiser to stick to security updates as soon as the system works just fine for their needs, as a general rule.

Your messages made me try gnome-maps. I have an up-to-date system, gnome-map is crashing in less than one minuted as you have reported.
I did the purge, autoremove and reinstall as you suggested and here I am:
(org.gnome.Maps:7317): folks-WARNING **: 09:39:43.694: Failed to find primary PersonaStore with type ID 'eds' and ID 'system-address-book'.
Individuals will not be linked properly and creating new links between Personas will not work.
The configured primary PersonaStore's backend may not be installed. If you are unsure, check with your distribution.
***MEMORY-ERROR***: org.gnome.Maps[7317]: GSlice: assertion failed: sinfo->n_allocated > 0
Note: I am not in a MATE session, I am using only dwm.
If you keep fully updating your system, you will keep bringing Maps back to the future, where the crashes happen.
EDIT: If you want to keep getting all updates *but* those related to Maps, you are probably going to need to lock the package version. I never needed to do that, so I am not in a position to recommend it, but you may want to try. Synaptic provides an option to do just that in the "Package" menu. I have no idea whether this also has to be applied manually to all dependencies, which is seemingly where the regression was introduced.

Ah, I previously did not understand that "stick to security updates" meant to not install other kinds of updates. What would be the way to do that? Only have aramo and aramo-security in /etc/apt/sources.list? Is there a way to revert to that without reinstalling Trisquel?
We could try to isolate the issue and try to fix it too :)
Oh yes, I subscribe to that option too. The issue report is in the making, mostly by way of collating the above info into a coherent text.
Also, researching upstream bug reports, especially those where Captain Haddock seems to be saying they would not fix 42.x crashes because they have now moved on to much better stuff GTK4, throwing away 'clutter' in the process:
https://gitlab.gnome.org/GNOME/gnome-maps/-/issues/423
https://gitlab.gnome.org/GNOME/gnome-maps/-/issues/585
UPDATE: issue report created for Aramo.
Hi prospero! Apologies for the off-topic question, but you did something there I have been trying to do without success.
How do we cross/cancel text in one of our older messages? As you did here --> "much better stuff"
This would be the strike tag:
<'strike'> This text will be very crossed if you remove the single quotes <'/strike'>
For all the HTML tags allowed in this forum, see https://trisquel.info/en/filter/tips
Yes, see that page and notice that it says: "No help provided for tag strike."
Yes! Just saw this message after I answered your previous one.
Thank Magic Banana!! I think it was you who introduced me to the HTML tags page, that was a few months ago and I've been referring to it ever since!
Oh, I noticed some messages can't be edited, I imagine is to do with the time it was posted. Is there a way to edit slightly older messages?
- The first post in a thread can never be edited;
- A post cannot be edited as soon as it is replied;
- Whole threads are locked after some months (all those started until March, currently).
Thanks for making things clear, Magic Banana.
A post cannot be edited as soon as it is replied
This makes good sense and I can see why I can't edit that post.
Thank you Prospero, that is very handy!
<'strike'> is not in the 'Compose tips' list of tags, I think it would be great if it could be added there, that page is so useful!
Note: Had to add quotes too, as all the text after the opening tag was crossed when I previewed my message, even without the closing <'/strike'>. Single minded power!
Yes, I am actually doing just that, usually. You can simply select "Security updates only" in "Software and updates". With "Daily" checks, and "Download and install automatically" you are left with a rather safe system, without most of the (rare but always possible) regressions. I would not recommend choosing that option right after install, though.
I tend to keep doing full updates for some time, until everything just works smoothly, then revert to security updates. From time to time, because of a glitch, an issue report, or a wild need for novelty, I do a full update and see what happens. I have been doing that since Trisquel 7, and nothing horrible ever happened, but Maps got a nasty bug with the last update, so I did purge, autoremove and install the 'aramo' package version again. Then I reverted to "Security updates", until next time, etc.
Good, timely advice Prospero! I'll remember that, thank you! My system is purring and I like that a lot!
Exactly. Trisquel is a purring operating system, and many of us like to just let it pur.
I should add that "full updates" also includes backports, contrary to the slightly more conservative "recommended updates", which I believe is default settings. I really like to use the backported LibreOffice version, it feels like riding the bleeding edge from a comfy sofa.
I've went ahead and changed to "recommended updates", the purring continues! Yes, that is Trisquel, even when we are in paranoid mode it seems to adapt to the needs of the paranoia case :)
Good to hear about the excellent use for a comfy sofa when "full updates" is selected. Thank you!
I'm testing on a Trisquel 11.0 (Mate) up-to-date (no backports) and gnome-maps seems to be working fine.
Could it be a hardware issue?
Please share the steps to trigger this issue.
Steps to trigger this issue on Trisquel 11.0 with MATE, using Mesa Intel® HD Graphics 4000 (IVB GT2):
1. run apt update with security and recommended enabled
2. install Maps
3. run Maps and start moving the map or zooming in/out
After a few moves, Maps crashes.
Steps to escape this issue:
1. purge gnome-maps and autoremove (26+1 packages uninstalled)
2. switch to security updates only
3. install gnome-maps
Maps does not crash any more.
UPDATE: several times I thought the issue was gone, so I visited here to amend this thread. Then I clicked on Maps in the window list to check whether it was still there, and it crashed. Just now I got:
***MEMORY-ERROR***: org.gnome.Maps[7415]: GSlice: assertion failed: sinfo->n_allocated > 0

Free software is awesome.
This seems to be gone after the last kernel update. So maybe that was it.
I may keep the issue open a couple of days, until I can confirm on the other systems where the glitch also happened.
@Avron: can you confirm this is not present any more on your system after updating it, including recommended updates?
EDIT: on some systems, I had to update, purge/autoremove/reinstall gnome-maps and reboot a couple of times before the glitch was gone.

On my up to date system with all udpdates and backports, it still crashes in the same way.

is there something wrong with the version on Trisquel, or is a bug in the inherent program?
Try what a Debian person would call an 'oldstable' version.
I am not sure if that is even possible. You could get the deb
from the Debian website and manually install it.
This would at least eliminate what I have to say.
You could just install the newest version
of gnome-maps from the Debian package manager
website; and hope it works.
Get the architecture right though.
Downgrades are possible too, with a command like:
sudo apt install gnome-maps=42.0-1
I actually didn't know how to install a specific version through apt that way. Thanks

Another way is to install the Flatpak. If you have not the Flathub repository already set up and want its verified FLOSS subset, execute in a terminal:
$ sudo apt install flatpak
$ flatpak remote-add --subset=verified_floss flathub https://flathub.org/repo/flathub.flatpakrepo
Then, to install GNOME Maps:
$ flatpak install flathub org.gnome.Maps
(To have the very first application I installed with flatpak appear in the menu, I had to restart the graphical session.)
The recommended way is not to go out of repo. This means using the packages that can be found in the Trisquel repository, not in some random third-party repo full of non-free stuff. Why would anyone be asking for that?
As mentioned by Ark74 above, the main suggestion is to help solving the issue here, not to go for adventures in the wild. Maybe you can help us? Issue report: https://gitlab.trisquel.org/trisquel/package-helpers/-/issues/111.
Have you tried purge/autoremove/install again gnome-maps, without enabling backports?
I had to do it at least a couple of times, apply some more updates (with security and recommended enabled, but not backports) and reboot each time, before it stopped crashing consistently.
It is still crashing, though.
I just got the crash again, but just once. It used to crash every time, after any amount of time between a few seconds and half a minute.
I have noticed that the map is centered and zoomed at the same position as when it last closed/crashed, even after reinstall. So some data must be kept from one install to the next. I may try to purge all dependencies, I am not sure whether autoremove is doing as much cleaning as purge does. Clearly, the crashes now happen much less often, to the point that I thought they were gone.
Several packages do keep some config files at ~/.config or ~/.local
Apt will not touch files on user home directory, not even purging, so you might wanna delete those so you have a "new user" experience.
Regards.
Thanks, I tried to do that after autoremove --purge, but had forgotten to check ~/.local. There are indeed some Maps related files there. Removing them did not help, though. There is also a Maps path in the dconf editor, with a 'last-viewed-location' key. A custom value corresponding to the last position of the map was used, and updated as the map position changed. I tried to select the default value [0.0, 0.0] but it kept switching back to custom value each time I opened Maps. I removed that path manually after uninstalling Maps but it did not help either. I last got corrupted size vs. prev_size after doing all the steps above and installing again. Now it just keeps crashing like a drunk gnome trying to find its way in a dense forest with the wrong map. Note that version 42.3 is not adding any noticeable benefit to 42.0, none that I could notice between two crashes at least.
FoxtrotGPS: we can dance if we want to...
https://www.foxtrotgps.org
Dispirited by those endless crashes, I eventually discovered FoxtrotGPS. The last version is available in the Trisquel repository. It does not crash, it does not indulge in RAM hoarding, and it does not try to simulate continuous zooming between two discrete zoom levels. It does have several nice layers to select from, and it can easily save tiles for offline access. A graceful mapping app to save the day.
Is Marble still a thing?
Was it a KDE app?, right?
Indeed, but it is the most resource hungry of the three.
I initially thought I would simply switch to Marble, but it also crashed, although not repeatedly. I think it crashed while switching map layout, not while navigating a given layout. I did not try much further after noticing that reverting to Maps 42.0 prevents it from crashing. Then I found FoxtrotGPS.
FoxtrotGPS is still to crash.
