Description Dipta Biswas 2022-03-08 18:37:23 UTC

Application: plasmashell (5.24.2)

Qt Version: 5.15.2
Frameworks Version: 5.91.0
Operating System: Linux 5.16.12-200.fc35.x86_64 x86_64
Windowing System: Wayland
Distribution: Fedora Linux 35 (Thirty Five)
DrKonqi: 5.24.2 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
Running `kquitapp5 plasmashell && kstart5 plasmashell &` through krunner

- Unusual behavior I noticed:
When I was hovering over my application menu, mouse cursor was changing from Breeze to Adwaita (probably Wayland & XWayland issue)

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault

FWIW You can omit the "&" when using kstart5; it automatically opens the specified app in the background.
