Do you have some handy tool to look at the timestamps? I resorted to grepping
the output of GST_DEBUG=vorbisdec:5. Here's how things in the choppy case:

0:00:00.141078842 25871  0x947e940 DEBUG              vorbisdec

And here's what it looks like with vorbisparse upstream:

0:00:00.503789262 25888  0x97bae68 DEBUG              vorbisdec
