Sorry for the line-wrapping in the previous report. The crashes are still present and very frequent (5~10 times a day). I think those crashes only occur when a notification is to be displayed (and I have just successfuly crashed it using “notify-send test”), but it does not occur every time (and I am indeed unable to reproduce it anymore with “notify-send test”).
I have a few gnome-shell extensions enabled: Alternatetab, Application menu, Removable drive menu, Places status indicator and Pomodoro, all from Debian. Here is a more recent backtrace, mostly identical, but without line-wrapping: #0 0x00007f539e5cbcaf in g_type_check_instance_is_fundamentally_a () at /lib/x86_64-linux-gnu/libgobject-2.0.so.0 #1
