can't save changes in gwenview

I’m using opensuse 11 with kde 4.1 RC and my problem is that I can rotate the images in gwenview but then I can’t save the changes, I click the save button and nothing happens. when I close gwenview it asks me if I want to save the changes, if I click yes, nothing happens and the app remains open, so at the end I have the click in forget changes and quit.

Ant ideas hpw to solve this?
