[UIImageView _isChargeEnabled]: message sent to deallocated instance

I am getting this error message from an apparently private API. Anyone have a clue what this could be? It seems to occur, if you use MPMoviePlayerViewController and do a pinch while the movie is running. This will close the player, but afterwards the app crashes.

Only seems to be a problem with certain version of iOS (in this case iOS 3.2.2 on an iPad).

I found one post in another forum, but that did not really help, as with MPM开发者_开发问答oviePlayerController a different problem occurs.

FWIW, the issue is not the private API, it's that you've got a zombie object.
