I've tried reproducing your issue with my webcam and couldn't:
cvlc v4l:///dev/video0 --sout
'#transcode{vcodec=theo,vb=800,scale=1,acodec=vorb,ab=128,channels=2,samplerate=44100}:std{access=shout,mux=ogg,dst=source:hackyou at localhost:8000/live.ogg}'

but, I could see that the stream that gets out of my icecast has pts all
wrong, and no player seems to be able to correct them.

* does this happen with any capture source (try other machines, other
  capture cards)
* does this happen at particular times ? (i.e. in your log you read:
> DBUG stats/modify_node_event update node total_bytes_read (69615)

I got down to:
| DBUG stats/modify_node_event update node total_bytes_read (3117500)

without reproducing.)

* try splitting the problem, recording your muxed ogg from VLC to a
  file, and then streaming that (big) file back.
