Bug#930401: mutter: Crashes on restart if Static Workspaces are enabled (gnome-shell)

[Matthew Gabeler-Lee]

Package: mutter
Version: 3.30.2-7
Severity: normal
Tags: upstream

If you enable static instead of dynamic workspaces, then gnome-shell
segfaults if you restart it.

This has been reported and fixed upstream in 3.32.x, it would be nice if
this fix could be backported to Debian's 3.30.x release.

Note: I've put "gnome-shell" in the title in the hopes of making it
discoverable by web search, since the user perception is that this happens
when restarting gnome-shell, even though the upstream bug/fix is in mutter.
