Bug 281724

Application: digikam (2.0.0)
KDE Platform Version: 4.6.5 (4.6.5)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-11-generic i686
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
I was working on a RAW file picture and had been saving to a version of the original. I had the history screen up to see what filters were being used at the time. I went to save the file before going to the effects menu and it crashed and closed.

The crash can be reproduced every time.

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