Application: digikam (2.0.0-beta2)
KDE Platform Version: 4.6.00 (4.6.0)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-25-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
I had been moving files and renaming, creating and removing folders in Nautilus to see if the changes reflected in digiKam. Before that I viewed few images and added 3 tags to 2 images.

I was finished and decided to close digiKam (upper right corner), when at first it seemed unresponsive and Ubuntu's 'Application x is not responsing, force quit' appeared. I decided to wait and after few seconds the main window of digiKam disappeared and then Report crash appeared. 

I have the terminal output of digikam for this entire session if you want it.

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