I've found an upstream commit that might be the solution for all of these
crashes. Please try mutter 3.30.2-8 and gnome-shell 3.30.2-10 when they
become available in unstable. After upgrading you will need to log out
and back in (or reboot) for the new code to be used.

The actual fix is in mutter, but the updated gnome-shell has a different
crash fix, and while you're restarting GNOME anyway we might as well get
wider testing for the updated gnome-shell too...

(Lid-close/suspend seems to be treated as a monitor unplug internally,
which is why it can cause similar crashes.)
