Description Tony 2020-08-28 21:36:14 UTC

Qt Version: 5.15.0

Operating System: Linux 5.8.5-xanmod1 x86_64
Windowing system: Wayland

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

Plug a usb hdd.
From it tried to mount an ISO file by right click > Mount ISO.

Running file command shows this : 
BC1.iso : ISO 9660 CD-ROM filesystem data 'CDROM'

I can open and decompress the file with Ark as well as manually mount it with : mount -o loop "file" ~/Public.

The crash can be reproduced every time.

-- Backtrace:
Application: Dolphin (dolphin), signal: Aborted
