Sentry Crash Report:

Description Gábor Ziegler 2012-02-29 21:42:26 UTC 
Application: digikam (2.5.0)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-16-generic i686
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
Tagging unknown people afterface detection has just run. Detection has run over a small subalbum. Total databse size: 51k+ pieces photos, 50+Gb total albums, 1GB RAM, so digikam swaps frequently. Hyperthreaded CPU. Probably concurrency hazard due to slow system?

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

Comment 1 Marcel Wiesweg 2012-03-12 10:25:40 UTC 
Debug info is missing, but from the situation the crash it can be assumed that frame 12 is AssignNameOverlay::eventFilter and 7 is AssignNameOverlay::checkIndex.
But that does not really help me. Was this crash reproducible?
Comment 2 caulier.gilles 2012-06-22 08:51:55 UTC 
Official digiKam 2.6.0 release is out since few days now :

With next 5.1.0 release, a lots of investigations have be done around OpenCV
face module integration with digiKam Face Engine.
See bug #365202 history for details.
