Bug 474172

Application: systemsettings (5.27.6)

Qt Version: 5.15.10
Frameworks Version: 5.108.0
Operating System: Linux 5.19.0-50-generic x86_64
Windowing System: X11
Distribution: KDE neon 5.27
DrKonqi: 5.27.6 [KCrashBackend]

-- Information about the crash:
Instaling KDE Neon in VMWare Fusion (current version) on my 2018 MBP.  Initially it looked like it was just a blackscreen, but for some reason the resolution was seveal screens wide and very small.  I moved it over and picked a random smaller resolution bc i couldn't read anything.  I think it went to 1024x768.  Then I tried to set it to 1440x900 (the half scale of the MBP) and it crashes out.  Happens every time I attempt the change.

The crash can be reproduced every time.

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