Bug ID: 470321
Summary: dolphin crashed during creation and deletion of loop
devices
Classification: Applications
Product: dolphin
Version: 22.12.3
Platform: Gentoo Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: dolphin-bugs-null at kde.org
Reporter: alexey.min at gmail.com
CC: kfm-devel at kde.org
Target Milestone: ---
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
