Either only video is seen or only audio is heard when streaming with Phonon on N900

Start rstp streaming on N900 for example with the version of qmediaplayer that uses Phonon. When streaming starts only video is seen or only audio is heard but not both.

Potential tip: The behavior is similar to players that can pick up only one stream from the sdp header that comes with the stream. It seems only one of the two streames of the sdp header is started.
