FULL sudo journalctl -f -b output: https://pastebin.com/ZEiDb7mR
STEPS TO REPRODUCE
1. Lock the screen, and wait for the display to sleep as well (only the
display, the system dont)
2. Wake up the monitor, type password
3. Press the Caps Lock button when you type the password
OBSERVED RESULT
The kscreenlocker will be crashing instantly when i press the caps lock button,
and shows me this:
The screen locker is broken and unlocking is not possible anymore.
In order to unlock switch to a virtual terminal (e.g. Ctrl+Alt+F2),
log in and execute the command:
loginctl unlock...
EXPECTED RESULT
Nothing, just enabling caps lock as intended
