Bug 237896

Application that crashed: digikam
Version of the application: 1.2.0
KDE Version: 4.3.5 (KDE 4.3.5)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-21-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
Tagging pics causes crash.

I can't replicate exactly, but after anywhere from 1-10 pics, the application will crash.  This is extremely frequent.  This is typically after the following:

1) Open Digikam
2) In My Albums view, switch to folder containing 176 pics
3) Double click on a pic.
4) Add existing Tag : People\XXXX\XXXXX
5) Click Apply
6) Add another Tag : Things\Chairlift
7) Page Down
8) Crash

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