Application: digikam (7.4.0)

Qt Version: 5.15.2
Frameworks Version: 5.88.0
Operating System: Linux 5.15.11-grue x86_64
Windowing System: X11
Distribution: Debian GNU/Linux bookworm/sid
DrKonqi: 5.23.4 [KCrashBackend]

-- Information about the crash:
Compiled v7.4.0 from sources.

Crash happens when trying to copy photos from laptop drive to an external USB drive connected to the laptop. The drive is mounted, visible and has full read/write permissions.

Selected a large group of photos (approximately 800) in an album by left clicking on first photo.
<SHIFT> left click on last photo.
Left click and drag highlighted photos to new album.
Window opens asking whether to copy or move. Move is selected.
Seems to start moving then crashes with segfault.
Restart DigiKam.
Window open scanning for new photos.
As soon as this window closes DigiKam segfaults.
This second crash repeats everytime DigiKam is restarted. Had to resort to use Appimage bundle to have a usable program. I did not attempt moving the photos with the Appimage version.

The crash can be reproduced every time.

-- Backtrace:
Application: digiKam (digikam), signal: Segmentation fault
