I also just got this update, and it seems everything is now fixed in Hardy Heron Beta. Even with a flash player 9.0 tab open in my 64bit Firefox, I can still open Amarok without the previous error message. I think if a few others write in that its fixed, and you are able to get all error messages to go away Timo, we should mark this bug as fixed.
Can't rely on my results too much though, as I did both the package installs, and editing of .kde settings mentioned above.
