Application: digikam (2.1.1)
KDE Platform Version: 4.7.1 (4.7.1)
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:

had requested that digikam ignore existing unconfirmed face tags and rescan the collection. several pictures were scanned (many, many more to go though) and i canceled the search for faces.
next was digikam crashing and the crash reporting wizard taking its place.

-- Backtrace:
Application: digiKam (digikam), signal: Aborted
