Description Stefan Kretzschmar 2012-12-19 13:59:13 UTC 
Application: digikam (2.5.0)
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.1

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

-I ran the face-recognition
-digiKam asked me to identify some faces
-I selected some (appr. 150) Photos of the same person and clicked on the confirm-button
-digiKam was writing as usual the Meta-datas, but on a certain points (some minutes later-digiKam was still busy writing the Meta-datas) digiKam crashed (it just disappeared from the screen/the process disappeared)

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