I installed the gnome-panel-dbgsym package, and got this backtrace when
I set the preferences on the gnome-panel to show windows from all
workspaces. Based on further observation, it seems that the issue has to
do with something bad happening when notifications are sent to the
gnome-panel by apps. I have attached the stack traces, there doesn't
seem to be any more info though.
