Bug 432535

Application: systemsettings5 (5.20.5)

Qt Version: 5.15.2
Frameworks Version: 5.78.0
Operating System: Linux 5.10.11-200.fc33.x86_64 x86_64
Windowing system: X11
Distribution: Fedora 33 (KDE Plasma)

-- Information about the crash:
- What I was doing when the application crashed:
the application window closes and a message appears with the buttons "restart" and "error report".

- Unusual behavior I noticed:
go to "work environment behavior", then "screen locking", then the "configure" button; now select any other workspace settings tab and get an error.

- Custom settings of the application:
nothing.

The crash can be reproduced every time.

-- Backtrace:
Application: Параметры системы (systemsettings5), signal: Segmentation fault
