Comment 62 for bug 1714989

I'm running gnome-shell on upgraded Ubuntu 17.10 with X server, not Wayland, due to other compatibility issues.
In my case if I lock the desktop but the gnome-shell is restarted because of segfault it kills the lock screen and leaves the desktop completely open with the user logged in.

I therefore think that this bug as it manifests in ubuntu's gnome-shell should be upgraded to critical/security.

Thank you,
