  Target Milestone: ---

Application: dolphin (20.08.2)

Qt Version: 5.14.2
Frameworks Version: 5.74.0
Operating System: Linux 5.8.0-26-generic x86_64
Windowing system: X11
Distribution: Ubuntu 20.10

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

I went to Trash where I had about 400 MiB of data and attempted to empty the
Trash. Every item in Trash was duplicated, which I thought was strange. When I
hit "Empty Trash" button, Dolphin crashed.

The crash can be reproduced every time.

Application: Dolphin (dolphin), signal: Segmentation fault
