Bug description:
Hi all,
Originally I was reporting bug 1717170, about session crash after monitor
disconnect/switch-off/input change on desktop PC and the bug was fixed
according to bug tracker. But now, after gnome-shell and mutter update, the
crash goes worse. Now it is not just session kick-out but complete crash. Same
events can be used to reproduce the crash. This time also crash files was
created.
