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

I used advanced search to search for pictures with a color label (red, orange, yellow ...) Not sure how that's called in an English locale, I'm using a German version.

Maybe the error happended earlier, I also had a crash during tagging images. But now the crash is fully reproducible and happens always.

The crash can be reproduced every time.

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