Bug 460004

Application: dolphin (22.08.1)

Qt Version: 5.15.6
Frameworks Version: 5.98.0
Operating System: Linux 5.15.0-48-generic x86_64
Windowing System: X11
Distribution: KDE neon User - 5.25
DrKonqi: 5.25.5 [KCrashBackend]

-- Information about the crash:
I unmounted my external hard drive, which is LUKS encrypted, and dolphin crashed immediately.
I did not try again, but this should not happen.

The reporter is unsure if this crash is reproducible.

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