Bug 439320

Application: systemsettings5 (5.22.1)

Qt Version: 5.15.2
Frameworks Version: 5.82.0
Operating System: Linux 5.12.13-gentoo x86_64
Windowing System: Wayland
Drkonqi Version: 5.22.1
Distribution: Gentoo/Linux

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

In systemsettings navigate to Window management, Window behavior, Advanced tab. Change window placement from "Minimal overlapping" to "Centered", observe crash.

Lauch again, navigate same way, change from "Centered" to "Minimal Overlapping" - crash again.

The crash can be reproduced every time.

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