Application that crashed: digikam
Version of the application: 1.0.0
KDE Version: 4.3.5 (KDE 4.3.5)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-17-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
Repeatedly I would select an image in the viewer, select a tag on the right panel, and click apply.  After tagging a dozen or two images this way, digikam would crash.  This was reproduced four or five times.

 -- Backtrace:
