Description guenter 2014-05-10 12:42:50 UTC
Application: digikam (4.0.0-rc)
KDE Platform Version: 4.13.0
Qt Version: 4.8.4
Operating System: Linux 3.7.10-1.28-desktop x86_64
Distribution: "openSUSE 12.3 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
I started face detection with try of recognition. I mean, there are already faces detected and combined with names.
Process starts and crashes after about 2 seconds.

The crash can be reproduced every time.

-- Backtrace:
