Application that crashed: digikam
Version of the application: rc..-rc
KDE Version: 4.3.4 (KDE 4.3.4)
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:
I created several new tags on the left-hand tag pane.  After the sixth tag, the application segfaulted.  I can't reproduce this on a fresh start.

 -- Backtrace:
