Application: dolphin (21.12.2)

Qt Version: 5.15.3
Frameworks Version: 5.93.0
Operating System: Linux 5.17.9-300.fc36.x86_64 x86_64
Windowing System: Wayland

DrKonqi: 5.24.5 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
Dolphin was unfocused for a period of time with two tabs open. I switched from another application to Dolphin and it crashed.

Dolphin crashes in similar situations like this for me fairly regularly though I have yet to find some specific cause.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
