Well, I'd like to thank everybody for support, I finally decided to spent 4hours and revert back to a (luckily made) backup. Later I upgraded again and everything works well now. So I believe the cause was a broken upgrade process on my side (kdelibs,..) Talking about a clean .kde4, this is a common but radical solution, is there and easy way to perserve IM history, mails, kwallet passwords and whatnot.. or is this all hidden (and lost) somewhere in this dir and has to be copied manually?
