Public bug reported:
When I press the lock shortcut Gnome Shell won't lock screen: instead it
"blinks" (top bar disappears for a moment) and comes back, no lock
screen or password asked. Closing screen (laptop) does the same but I
still get low consumption, so hibernation seems to be working, but there
is no password asked after opening.
I get this error in dmesg:
```
[10413.140792] gnome-shell[28745]: segfault at fbc8 ip

```
I tried to "apt-get install --reinstall gnome-shell", or "uninstall
--purge" it and install back, but nothing works. It has started right
after an update 2 or 3 days ago, supposedly related to 19.04?
I obviously never disabled the password on lock screen :) by the way
it's working perfectly if I chose standard GNOME desktop on login.
