Bug 284528

Application: digikam (2.2.0)
KDE Platform Version: 4.7.1 (4.7.1)
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:
* Start digiKam
* Click on any picture to get to "View Image" mode
* On right panel open Colors tab with Histogram
* Hit Spacebar to see next picture -> digiKam is closed down immediately.

The crash can be reproduced every time.

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