AVPlayer crashing in StitchedStreamPlayer example when playing audio

Question

The StitchedStreamPlayer in Apple's documentation gives an example of how to stream video on the iphone. The example works fine for the example video given. However, if instead of a video, a link to an audio file is provided, such as this, the app crashes with the following assert, which seems to be coming from an assert of internal framework files.

To reproduce: On an iOS 6 device, in Settings:Developer:Network Link Conditioner - Status:ON/Very Bad Network Once the AVPlayerLayer is visible (it will be a black box since there is no video, only audio), press the play button and slide the scrubber.
