All is still not well. It's the amazing time-travelling ogg stream!

The "current time" claims to jump from 2:50 to 5:53 just after the snip. This
happens in between tracks when streaming
http://www.spogbiper.com:8000/stream.ogg after having removed the dodgy
segment_start calculations; this is either messing up, or is messed up by, the 
next chain's begin_time (I'm having trouble following the flow control in
gstoggdemux). Result is a 3 minute silence before anything is next heard.
Chains in the middle of tracks - I assume triggered by new metadata - are just
fine.

Based on the fact that I either haven't fixed the bug at all, or that there's
more than one bug at work, I'll shut up now until somebody cleverer than me
chips in. :)
