            Bug ID: 417892
           Summary: Dolphin crashed when ejecting used disc
           Product: dolphin
           Version: 19.12.2
          Platform: Archlinux Packages
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: dolphin-bugs-null at kde.org
          Reporter: chris-r at posteo.net
                CC: kfm-devel at kde.org
  Target Milestone: ---

Application: dolphin (19.12.2)

Qt Version: 5.14.1
Frameworks Version: 5.67.0
Operating System: Linux 5.5.4-arch1-1 x86_64
Windowing system: X11
Distribution: Arch Linux

-- Information about the crash:
- What I was doing when the application crashed:

I tried to eject a blu-ray disc. I had opened it in VLC media player and tried
to eject it immediatly after closing VLC. Dolphin crashed (and the disc was not
ejected).
The disc was still spinning at that moment. When waiting some time (until the
disc spins no more), dolphin ejects it as requested and does not crash.

The crash can be reproduced every time.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
