Bug 470321

Application: dolphin (22.12.3)

Qt Version: 5.15.9
Frameworks Version: 5.106.0
Operating System: Linux 6.3.2-gentoo x86_64
Windowing System: X11
Distribution: "Gentoo Linux"
DrKonqi: 5.27.5 [KCrashBackend]

-- Information about the crash:
I was running postmarketOS bootstrap tool (pmbootstrap) and it creates filesystem images by creating loop devices, mounting them, formatting, copying files and umounting. I suppose bug is somewhere in solid in device enumeration?

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
Content of s_kcrashErrorMessage: std::unique_ptr<char []> = {get() = 0x0}
