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
