GTG core dump at startup

[ksdrummer]

Hi, I have this problem since few weeks but didn't have time to open a bug.
I opened a new one because I don't have the same error messages than #968 #962 or #963 (but feel free to close this one if it's related)

Happens every-time :

I'm running archlinux up to date with GTG from AUR.
GTG (Getting Things GNOME!) 0.6.0

Can you get a backtrace from GDB? See #961

[ksdrummer]

Yes, I'm trying but I never used gdb before and something is not working :

What am I doing wrong ?

[Neui]

Oh I noticed I didn't included that. Run gdb --args python3 /usr/bin/gtg --debug (and accept that debuginfod just in case), and when you have the (gdb) prompt, run run to run GTG normally, and when it crashes you should see (gdb) prompt again, in which you can run bt (and then quit to quit).

[ksdrummer]

Ok thank you for the explanations.

It seems now that it doesn't crash every time. But when it does :

This appears to be the same issue as #961.

As a workaround, do: #961 (comment)

Open ~/.config/gtg/gtg.conf in an plain-text editor such as GNOME editor, vim or whatever you like, and under [browser], find a line font_name = and change it to font_name = Sans 11.

This changes the font of the task editor. You can change it later in the settings.

Yes it seems to have solved it. Thanks a lot ! Sorry for not having found #961
