you need to has wrestool and dolphin using it to show windows executable icon to easily reproduce this issue.

New crash information added by DrKonqi

dolphin (20.12.2) using Qt 5.15.2

- What I was doing when the application crashed:
Ejecting DVD from Dolphin causes crash. Trying to eject the disc from Plasma Devices Status Bar it won't work either, but does not cause a crash. Third party apps are still capable to eject (tested Nero 4 Linux, K3b, Brasero)

- Unusual behavior I noticed:
Dolphin showed duplicate entries for the same DVD when I first inserted it while Dolphin was still open.
