Bug 485510

Application: systemsettings (6.0.3)

Qt Version: 6.7.0
Frameworks Version: 6.1.0
Operating System: Linux 6.8.6-zen1-1-zen x86_64
Windowing System: X11
Distribution: "Arch Linux"
DrKonqi: 6.0.3 [CoredumpBackend]

-- Information about the crash:
In System Settings > Color & Themes > Login Screen (SDDM) > Behavior,
check the box to enable automatic login, then exit System Settings and it will crash without applying the setting.
In addition, the 'Apply' button is greyed out and can't be clicked.

This happens with kcmutils 6.1.0, but not 6.0.

The crash can be reproduced every time.
