Bug 278890

Version:           2.0.0 (using KDE 4.7.0) 
OS:                Linux

There are two builds:
digikam-2.0.0-rc built with qt-4.7.3 and KDE 4.6.90 http://koji.fedoraproject.org/koji/buildinfo?buildID=251991

and digikam-2.0.0 built with qt 4.8 beta1 and KDE 4.7.0 http://koji.fedoraproject.org/koji/buildinfo?buildID=256199

Crashes only second build digikam-2.0.0.
So if there is no any regressions then maybe this crash related with qt 4.8.

Reproducible: Always

Steps to Reproduce:
showfoto crashes in Apply Texture filter (and other filters)
when moving Relief slider.



Actual Results:  
 

Expected Results:  
 

Application: showFoto (showfoto), signal: Segmentation fault
