Sometimes (latest days at least one time a day), the gnome session

Only way to come back to usable state is going into a console window
(Ctrl+Alt-F2), searching for gnome-shell process id and run
kill -SIGHUP<pid>
Then come back to X windows system session that has become usable
again (Ctrl+Alt+F2 and come back to X doesn't give any result if I
don't kill sighup gnome-shell)
Sounds like a bug in gnome-shell, at first blush.
If you debuginfo-install gnome-shell, attach with gdb instead of sending
SIGHUP, and run 'thread apply all backtrace', what do you get?
