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".
