aac - failure decoding audio stream when audio configuration changes

After testing early Freeview HD support with MythTV, on some recordings on audio would stop partway through the recording. This typically happens on program start/end and the following error is reported:
[aac_latm @ 0xf13bc0]channel element 0.0 is not allocated
Using a recorded file, both VLC and Mplayer exhibit the same problem, which indicates FFMpeg as the likely source. What appears to happen is there is a change in audio configuration in some of the streams from stereo to six speakers and back again. FFMpeg can decode both configurations fine, but fails if a transition occurs mid-stream.
I've posted a 50MB clip that exhibits the problem at:
The audio decodes fine for the first three quarters of the clip, and then fails when the program starts.
