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, most formats play without any issues, however FLAC files fail
to play. A similar bug involving Ogg Vorbis was recently fixed
(https://bugzilla.gnome.org/show_bug.cgi?id=675812), however the problem with
FLAC seems unaffected by this fix and pre-dates the point at which the Ogg
Vorbis bug was introduced in 0.10.35.

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, Ogg Speex or Ogg Vorbis
file (using the current version in git or pre 0.10.35) it should play
correctly, however when it is set to a FLAC file an internal data stream error
will occur.

Using the script with a FLAC file produces the warnings:
