Application: dolphin (20.08.2)

Qt Version: 5.14.2
Frameworks Version: 5.74.0
Operating System: Linux 5.8.0-31-generic x86_64
Windowing system: X11
Distribution: Ubuntu 20.10

-- Information about the crash:
- What I was doing when the application crashed:
Opened dolphin and changed to directory, where i have just created 3 new files (.jpg with darktable). These 3 new files were shown duplicated with the same name. After pressing F5 (refresh) dolphin crashes. After new start it may happen, that the files where again showed doubled, but after some tries it is fine.

The crash can be reproduced sometimes.

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