XMMS won't play oggs

[Curtis Call <curtiscall@usa.net>]

Lately XMMS has been having problems when I try to play ogg vorbis files. 
When I try to select a file (using the Play File menu command) it just returns
with no file listed in XMMS.  MP3's still play fine.  I've tried uninstalling
and reinstalling XMMS to no effect.  Are the ogg vorbis handling routines
external to XMMS?  Any ideas?  I'm using v 1.2.7

Thanks
