Hi Michael , Olivier , The upload -4 of kdebase was only done to include a patch in kwin (36_kwin.diff), that was supposed to fix some crahes, but i can see it is provoking another differents :( Anyway, i think we could leave this patched version some days more, to see how much people reports problem (and because it is Xmas too :) ), and then study the situation.
