Description AiratHalitov 2020-08-30 14:40:22 UTC 
Application: plasmashell (5.18.5)

Qt Version: 5.12.8
Frameworks Version: 5.68.0
Operating System: Linux 5.4.0-42-generic x86_64
Windowing system: X11
Distribution: Ubuntu 20.04.1 LTS

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

1) create two folders "1" and "2" and file "3" on desktop
2) move folder "2" into folder "1"
3) move file "3" into folder "2" (which shold be in folder "1")
4) try to move file "3" to desktop from folder "2" with using quick folder view
5) you will see crash and file "3" won't be moved to desktop.

- Unusual behavior I noticed:
crash

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
