Description Till Seifert 2020-10-28 12:06:19 UTC
Application: dolphin (20.08.2)

Qt Version: 5.15.0
Frameworks Version: 5.75.0
Operating System: Linux 5.4.22-050422-generic x86_64
Windowing system: X11
Distribution: KDE neon User Edition 5.20

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

is was refreshing (F5) a folder (tree-view) with some folders expanded and some (not many) files in subfolders visible.
The folder refreshed and displayed some files in the expanded subfolders twice. About 1s later dolphin crashed.


- Unusual behavior I noticed:

this only happened with sftp so far, never with local folders.

The crash can be reproduced sometimes.

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

After seeing many duplicated entries in an sftp-mouted folder, I refreshed the contents. Dolphin crashed.

I can confirm that behaviour, it happen to me also on a local folder.  When I am scrolling up an down a folder with a larger amount of files or subfolders, suddenly some entries appear double.  After refesh, Dolphin crashes.
