Error loading Audio Framework?

I do not get the following with iOS 4.3, but just with 5+.

I somehow have the feeling it's related to the fact that my Project uses AVPlayer and that there are some bugs in the Apple code. But, in truth, I really do not have a clue. BTW, I have the AVFoundation framework in the Project.

Can anyone help, Please:

It is really much longer than the above, so I just presented the beginning.

Thanks again.
