Package: gnome-shell
Version: 3.36.2-1
Severity: important
heya, since yesterday under Debian/testing gnome-shell crashes (and then
restarts) when trying to lock screen. Here's the diagnostic I can find under
journalctl:
giu 02 17:17:32 noziere kernel: gnome-shell[106365]: segfault at 0 ip 00007fb2305fd467 sp 00007ffd001db960 error 4 in libst-1.0.so[7fb2305de000+4a000]

giu 02 17:17:32 noziere systemd[1768]: Starting GNOME Shell on X11...
It happens systematically, both when trying to lock screen on demand
(Ctrl+Alt+L) and when the laptop suspends (meaning that when it wakes up the
desktop is happily unlocked... this might make this bug warrant a security +
severity bump: I'll let this up to the maintainers to decide).
As shown above the shell immediately restarts afterwards, without causing any
session disruption/logout/etc.
Thanks for maintaining GNOME in Debian!
Cheers
