Title:
gnome-shell crashed with SIGSEGV in g_type_check_instance_cast()
Status in gnome-shell package in Ubuntu:
New
Bug description:
This happens all the time. Multiple times per day. No idea what
triggers it. Gnome-shell just randomly crashes. Thankfully I'm still
running Xorg. I can't imagine switching to Wayland and having my
entire session destroyed each time Gnome Shell crashes! I have no
further information and cannot reproduce this with a particular
action, but it happens at least once a a day now.
