Python script implementing a pipeline capable of reproducing this issue

In Jokosher we have a gnonlin composition which may contain various different
formats of audio, as of 0.10.36 (and possibly 0.10.35) Ogg Vorbis files no
longer play in this pipeline. Wave, MP3 and Speex files all continue to play
without any issues. With 0.10.34 Ogg Vorbis worked correctly.

Playing Ogg Vorbis files directly through a playbin still works correctly.

I've created a quick python script (attached) which implements a simplified
version of this pipeline and which can be used to reproduce this issue. When
the uri for the uridecodebin is set to a Wave, MP3 or Ogg Speex file it should
play correctly, however when it is set to an Ogg Vorbis file an internal data
stream error will occur.

When playing an Ogg Vorbis file the following warnings are produced:
