Application: digikam (2.0.0-beta5)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
I closed the digiKam window (and the application) from the top right corner. Before closing I had been using face regocnition in assigning tags to images, usually confirming multiple faces at a time. I also moved few images inside digiKam from album to another. 

This crash is similar to bug 266086, which was filed against beta2, in that it occured after closing digikam. Haven't tried reproducing yet.

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