Bug 440643

Application: systemsettings5 (5.22.4)

Qt Version: 5.15.2
Frameworks Version: 5.83.0
Operating System: Linux 5.13.6-200.fc34.x86_64 x86_64
Windowing System: Wayland
Drkonqi Version: 5.22.4
Distribution: Fedora 34 (KDE Plasma)

-- Information about the crash:
In System Settings I enabled the following option:

Window Management -> Window Behaviour -> Advanced -> Window Placement -> Centered

After pressing apply System Settings crashed.
I can recreate the crash, as it occurs every time.

The setting does actually get applied, even though the program crashed.

The crash can be reproduced every time.

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