            Bug ID: 445150
           Summary: Settings program crashes (seg fault)
           Product: kde
           Version: unspecified
          Platform: Fedora RPMs
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: aaruni at edufor.me
  Target Milestone: ---

Application: systemsettings5 (5.22.5)

Qt Version: 5.15.2
Frameworks Version: 5.87.0
Operating System: Linux 5.14.16-301.fc35.x86_64 x86_64
Windowing System: Wayland
Drkonqi Version: 5.22.5
Distribution: Fedora Linux 35 (KDE Plasma)

-- Information about the crash:
- What I was doing when the application crashed:

Experienced multiple times in different frames. To reproduce : enter settings
program -> workspace behaviour -> screen edges. change a setting, hit apply.
System settings crashes.

Also crashes when changing a setting in virtual desktops. Have not tried the
rest of the settings yet (workspace is near the top of the list of settings).

Possibly system settings crashes when applying changes on a Wayland desktop?

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
