Application: showfoto (1.7.0)
KDE Platform Version: 4.5.5 (KDE 4.5.5) "release 1"
Qt Version: 4.6.3
Operating System: Linux 2.6.34.7-0.7-desktop i686
Distribution: "openSUSE 11.3 (i586)"

-- Information about the crash:
Issue when I call Enhance - Lens - Auto Correction.
The window appears a very short time, then application crashes.
(I could not even choose lens type, or any parameter) 
I reproduced it in various conditions : with full folder loaded, with single picture loaded, as first action, after doing other actions (like color correction...)

The crash can be reproduced every time.

-- Backtrace:
Application: showFoto (showfoto), signal: Segmentation fault
