Application that crashed: digikam
Version of the application: 1.2.0 (rev.: 1086154)
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-17-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
I was recreating bug 226515 for testing. After removing a tag assigned to an image (as in 226515), the  right sidepanel Caption/Tags "My Tags" -window only includes a single item "My Tags", not the keyword hierarchy. 
Application crashes when one uses the left sidepanel to show only some subset of the images, eg. one album, spesific keyword. New for me is that sometimes the box beside "My Tags" is checked.
Using the right sidepanel is ok, although it seems to be partially locked, not all options are available for use. The menus work even if the My Tags window only has one item.

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