Bug 447799

Application: dolphin (21.08.3)

Qt Version: 5.15.2
Frameworks Version: 5.89.0
Operating System: Linux 5.15.11-200.fc35.x86_64 x86_64
Windowing System: X11
Distribution: Fedora Linux 35 (KDE Plasma)
DrKonqi: 5.23.4 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
Dolphin crashes sometimes when trying to eject a real disc while it is busy. When I force to eject by pressing the button sometimes the system can also hang and Terminal is really sloppy, shutdown isn't working or is very slow. (much rarer)

System: Fedora 35 KDE Spin

The crash can be reproduced sometimes.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
Content of s_kcrashErrorMessage: std::unique_ptr<char []> = {get() = <optimized out>}
