After a recent update (probably from GStreamer 1.12.0 to 1.12.1) GStreamer-based media players no longer play many of my Ogg Vorbis files.  An example, with the attached foo.ogg:

$ gst-play-1.0 foo.ogg
Press 'k' to see a list of keyboard shortcuts.
Now playing /tmp/foo.ogg
ERROR Could not decode stream. for file:///tmp/foo.ogg
ERROR debug information: gstvorbisdec.c(352): vorbis_handle_header_packet (): /GstPlayBin:playbin/GstURIDecodeBin:uridecodebin0/GstDecodeBin:decodebin0/GstVorbisDec:vorbisdec0:
couldn't read header packet (-132)
Reached end of play list.

ogginfo doesn't report any problems with the file, but FFmpeg does:

$ ffmpeg -v error -i foo.ogg -f null -
[Vorbis parser @ 0x55de9d387700] Invalid packet

Despite this, FFmpeg-based players can still play the file.

I suppose that if the Vorbis files aren't to spec, then technically it's OK for GStreamer to fail.  But it had been playing them perfectly and without complaint for the last 15 years, so it's a bit annoying that it's suddenly refusing to play them now.  Is there any chance that the old behaviour could be restored, so that GStreamer at least *attempts* to play the Vorbis files rather than failing outright?

This problem may be related to Bug 784530, which is about GStreamer refusing to play Vorbis streams with a different kind of corruption.
