[icecast] Ices re-encodes have died

Hi:

As an adendum, we restarted ices without touching icecast.  All three
streams came up and seem to be stable.

I note from the stats page that the two re-encoded streams died on the same
song.  Here is the output of ogginfo running on that file.  Note the stuff
at the bottom.

Processing file
"/var/music/Emerson,_Lake_&_Palmer/Pictures_At_An_Exhibition/11-The_Great_Gates_Of_Kiev._The_End.ogg"...

We've no idea how this came about.  The guy who ripped it uses ABCDE which
calls oggenc to do the encoding.  The vendor tag suggests that the oggenc
used is that which is contained in vorbis-tools 1.0.1.  The rip was
apparently done during the last week in december.  the really odd thing is
that tracks 10 and 11 are affected like this, whereas tracks 1-9 and 12 are
fine.

anyway, I guess that's possibly what put ices into a weird state.

Geoff.
