Note if you're debugging midori when this happens the SIGSEGV causes X to freeze until you gdb kill midori.
I've searched upstream both in midori and webkit and I can't find the bug listed there.

The above method doesn't recreate the problem all the time. A more reliable method is to click on Edit in the second window. Go back to the first, select some text on the webpage, then click Edit.
The problem occurs in fresh installs of both the amd64 and i386 versions of trisquel-mini_7.0-20140831 . The machines in question have different GPUs, (nVidia - amd64 and Intel - i686).
Here's a proper backtrace

I'm lowering the priority as this isn't a Midori show stopper.
Also assigning the bug to myself as to indicate I'm doing work investigating, collecting diagnostics etc as a back burner task.
This isn't present in Lubuntu 14.04.1 at current service level nor with the ppa used as the source of the Trisquel Mini Belenos version.
Returning this to normal priority because I think Trisquel originated bugs should be fixed in a beta and minor class bugs can sometimes be left unfixed. Also unassigning myself until I've spoken to quidam as he might well fix it before I talk to him.
