sysinfo crashes when trying to view "System" section (other sections work ok)

Category:bug report

Installed sysinfo from Trisquel 8/Flidas repositories: sudo apt install sysinfo

Program starts up but will not display the "System" section - crashes and closes itself when this section is selected.

I tried this on two (very) different systems, an HP laptop with a Pentium/Atom processor and on an X79 Xeon server; same results with both.

Running "sysinfo" from the command line (in order to see its output) reveals the following when the user clicks on the "System" section:

Upstream sysinfo bug #9 addresses this, posting a possible patch to fix the issue:

I'm getting the same error. Alternatives, such as Hardinfo, work fine.
