Sentry Crash Report:

Description qwertzmd 2010-04-03 21:15:39 UTC 
Application that crashed: digikam
Version of the application: 1.2.0
KDE Version: 4.3.5 (KDE 4.3.5)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-16-generic i686
Distribution: Linux Mint 8 Helena - KDE Community Edition

What I was doing when the application crashed:
Looks a bit like the same behaviour in 1.1.0. I was check-marking tag information (with existing tags) such as people visible on the image, the clicked "apply" and then Digikam crashed. This crash seems to happen less frequently than in 1.1.0.
