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 fffffffffffffbc8 ip 00007f37ab2c6ec8 sp 00007ffdc4a371d0 error 5 in libst-1.0.so[7f37ab2a0000+2b000] [10413.140798] Code: 00 00 48 8d 3d 57 78 00 00 e9 34 9c fd ff 0f 1f 40 00 41 57 41 56 41 55 41 54 55 53 48 83 ec 28 48 63 1d db 74 01 00 48 01 fb <48> 8b 6b 08 48 85 ed 74 17 48 83 c4 28 48 89 e8 5b 5d 41 5c 41 5d ``` 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.
