Ok, here we go. It is in atspi... But I have no debugging symbols for that. Seems I'll have to compile it myself, right? The gdb.txt is attached.
I'm not sure, Does the package libatspi2.0-dev help? The bug seems this one : https://bugzilla.gnome.org/show_bug.cgi?id=767074You could add a comment on the GNOME bug tracker with your steps and ask them for the debugging process if needed.
