Operating System: Linux 2.6.32-25-generic i686

-- Information about the crash:
I tried to update DigiKam to newer version (according to guide found on http://scribblesandsnaps.wordpress.com/2010/06/24/install-the-latest-version-of-digikam-on-ubuntu-10-04/). App crashes from than on, even after uninstaling and reinstaling version from Software Center. 

The crash can be reproduced every time.
