Actually I could reproduce it using both xmms (1.2.10) and ogg123, and 
it would crash at the exact same place in vorbis_book_decodevv_add.

I followed Michael's advice and upgraded to libvorbis 1.1.0, compiled 
with debugging info. So far it's running fine but I haven't let it run 
for very long yet. If it turns out that upgrading actually fixes the 
problem, maybe I'll try to downgrade it back to libvorbis 1.0.1 in order 
to track down what's really happening if you're interested.

Thanks for your input, I'll keep you updated.
