KDE 4.5.2 & fonts

Not sure what i did, but my fonts everywhere looks like courier now. Not rendered at all.
I tried it with selecting with render and without, but no difference.
I even tried to remove my .kde folder, but result were the same. Does anyone have a clue how i can fix it again?

I run opensuse 11.3 64bit.

Just to let everyone know. I solved it.
This is how i did it, but i still don’t know why my fonts did not work anymore.
