Application: dolphin (20.12.0)

Qt Version: 5.15.2
Frameworks Version: 5.77.0
Operating System: Linux 5.4.0-58-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:

1. Created new digikam library.
2. Pointed digikam at a folder under my home/user directory. This folder happens to be a ZFS file system (https://zfsonlinux.org/). Underneath each folder are separate folders roughly 2000 images per folder. Each one contains image types of raw, jpeg, xmp, tif, png
3. After initial import was working for about 5 mins, digikam crashed.
4. I keep trying to relaunch digikam, including restarting my computer, but digikam crashes again after just a few seconds

The crash can be reproduced every time.

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