Bug 285444

Application: digikam (2.1.1)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-12-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
I was adding a new region for a new face and than digikam crashes. This happens more frequently when face detection is running in the background (not in the case of this report)

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