gstreamer transcoding with wavparse and vorbisenc fails

I can play this wav :

http://freewavesamples.com/yamaha-sy35-clarinet-c5

gst-launch filesrc location=Yamaha-SY-35-Clarinet-C5.wav ! wavparse ! autoaudiosink

So I assume that wavparse is functioning properly, but this pipeline fails to transcode :

gst-launch filesrc location=Yamaha-SY-35-Clarinet-C5.wav ! wavparse ! vorbisenc ! filesink location=out.ogg

with the following warnings and errors

Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
0:00:00.028608695 23692       0xa99720 WARN                wavparse gstwavparse.c:2110:gst_wavparse_loop: error: Internal data flow error.
0:00:00.028637670 23692       0xa99720 WARN                wavparse gstwavparse.c:2110:gst_wavparse_loop: error: streaming task paused, reason not-linked (-1)

Strangely, the error is occuring in wavparse, so it is fine when the pipeline ends with an audio device sink, but not with an encoding sink...

try this pipeline: gst-launch filesrc location=audio.wav ! wavparse ! audioconvert ! vorbisenc ! filesink location=out.ogg

I think the format it doesn't supported in vorbisenc example (audio/x-raw-float) vorbisenc support (audio/x-raw-int), that why you should add audioconvert. You can see all details if you add -v option in your pipeline.
