Application that crashed: digikam
Version of the application: 0.10.0
KDE Version: 4.2.96 (KDE 4.2.96 (KDE 4.3 RC2))
Qt Version: 4.5.0
Operating System: Linux 2.6.28-13-generic x86_64
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
I selected one photo and used Batch tools -> Image color -> Normalize. I just wanted to try how it worked before processing all other pictures in the same folder. Once the process was finished, I click on OK button and Digikam crashed. 

 -- Backtrace:
