New Revision: 3509

Modified:
   liboggz/trunk/src/tools/oggzinfo.c
Log:
fix crash in oggzinfo if a skeleton track refers to a track not
found in the physical stream (while a skeleton track like this is
moderately useful, it can happen if you demux tracks and oggzinfo each
of them). Patch by ogg.k.ogg.k
