Bug ID: 393390
Summary: Dolphin crash after mounting ISO with CDEmu
Product: dolphin
Version: 18.04.0
Platform: Archlinux Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: normal
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Target Milestone: ---
Application: dolphin (18.04.0)
Qt Version: 5.10.1
Frameworks Version: 5.45.0
Operating System: Linux 4.16.3-1-ARCH x86_64
Distribution (Platform): Archlinux Packages
-- Information about the crash:
- What I was doing when the application crashed:
I was trying to mount a DVD ISO with CDemu. Once it was mounted, I got the
following message when I tried to access the virtual device from Dolphin:
"An error occurred while accessing '[title of the DVD]', the system responded:
The requested operation has failed: Error mounting /dev/sr1 at
/run/media/magiblot/[title of the DVD]: wrong fs type, bad option, bad
superblock on /dev/sr1, missing codepage or helper program, or other error"
(probably a problem with the ISO or CDemu).
The crash happened after unmounting and mounting the virtual device several
times, just after I picked the ISO again in CDEmu for the last time, without me
interacting with Dolphin. It actually crashed while it was in the background.
The crash can be reproduced sometimes.
-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
