New Revision: 3681

Modified:
   liboggplay/trunk/src/liboggplay/oggplay_callback.c
Log:
Also treat a zero granulerate from oggz_get_granulerate() as a zero
granuleperiod to avoid a floating point exception.

I haven't tested this, but a stream with a zero granulerate is 
conceptually one that is all headers, like a skeleton stream so
actual time based decoding should ignore it.
