Description Laurent RINEAU 2022-02-10 11:57:21 UTC

Application: systemsettings (5.24.0)

Qt Version: 5.15.2
Frameworks Version: 5.90.0
Operating System: Linux 5.16.7-200.fc35.x86_64 x86_64
Windowing System: Wayland
Distribution: "Fedora release 35 (Thirty Five)"
DrKonqi: 5.24.0 [KCrashBackend]

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

1. Start "Display Configuration" either from the start menu or from krunner
2. Then type the Esc key

that crashes the windows and Dr Konqi displays a notification.

Note that I run the KDE sesision with wayland, and I have two monitors: one integrated laptop manitor, and an external monitor.

The crash can be reproduced every time.

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