Description Gareth 2011-06-16 16:32:41 UTC 
Application: digikam (2.0.0-rc)
KDE Platform Version: 4.6.3 (4.6.3)
Qt Version: 4.7.2
Operating System: Linux 2.6.35.4-28.fc14.i686 i686
Distribution (Platform): Fedora RPMs

-- Information about the crash:
Trying to recreate another bug..., updated GIT to include commits up to 16th and compiled from scratch. 
Started digikam. All photos had been scanned already, and showed I think ~70 untagged unknown. This folder/tag view was open. Selected scan for faces, and selected to scan only those not scanned already. Completed without any new photos (expected). 
Then selected to scan for faces again, and this time selected to rescan all unknowns. Scan started. I then selected an image in thumbnail view, started to type a name, selected the correct tag by double clicking... crash.

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