Application: digikam (1.2.0)
KDE Platform Version: 4.4.2 (KDE 4.4.2)

Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
I had some duplicate tags (similar names) so:
1. Select on the unwanted duplicate tag
2. Add the correct tag
3. Remove the unwanted tag
4. Apply
5. Configured for write back to meta data so wait for that to finish
6. Delete the unwanted tag from the left hand, filter by tag window. It crashes. If deleting using the tag seeting display on the right then there is no crash.

I have a lot more similar duplicate tags to sort out so I will attempt to characterise this more exactly. I have seen this crash before and I think that it is reproducible.

The crash can be reproduced some of the time.
