Bug 469125

Application: systemsettings (5.27.4)

Qt Version: 5.15.9
Frameworks Version: 5.105.0
Operating System: Linux 6.2.13-arch1-1 x86_64
Windowing System: X11
Distribution: Arch Linux
DrKonqi: 5.27.4 [KCrashBackend]

-- Information about the crash:
- Open System Settings app
- Go to Shortcuts > Custom Shortcuts
- Change one of my custom shortcuts (e.g. comment, trigger or action doesn't matter)
- Then try to go away from “Custom Shortcuts” to “Shortcuts” without applying the change(s)
- And as soon as you click the “Discard” button on the “Apply Settings” dialog, the app crashes everytime

The crash can be reproduced every time.

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