Bug 435346

Application: dolphin (20.12.3)

Qt Version: 5.15.2
Frameworks Version: 5.80.0
Operating System: Linux 5.11.6-1-default x86_64
Windowing System: X11
Drkonqi Version: 5.21.3
Distribution: openSUSE Tumbleweed

-- Information about the crash:
- What I was doing when the application crashed: I opened the download folder during a download. Some times later i can see duplicate entries of one ore more files (but there is only one file!) At the next mouseclick (change a folder or mark a file) dolphin crashes

The crash can be reproduced every time.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
