            Bug ID: 452783
           Summary: System Settings crashes when opened from notification
                    bar
           Product: kde-cli-tools
           Version: 5.24.4
          Platform: Ubuntu Packages
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: aleix...@kde.org
          Reporter: m...@leyva.me
  Target Milestone: ---

Application: kcmshell5 (5.24.4)

Qt Version: 5.15.2
Frameworks Version: 5.92.0
Operating System: Linux 5.13.0-39-generic x86_64
Windowing System: X11
Distribution: Ubuntu 21.10
DrKonqi: 5.24.4 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
I stepped away from a moment and came back to a locked desktop. When I move my
mouse I was greeted with a message saying that the screen locker had crashed
and I had to unlock it via TTY2 by running "loginctl unlock-session 3." I did
and when I switched back to Plasma, I get a notification that KWin had
restarted due to a graphical issue. When I clicked on the notification to open
the system settings application, the crash occurred.

- Unusual behavior I noticed:
Screenlocker crashed and I had to unlock via TTY2.

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: System Settings Module (kcmshell5), signal: Aborted
