That's a known problem due to a stupid bug in 1.2beta1 (see earlier post
on the list).

Can you try the following patch: https://trac.xiph.org/changeset/11882
Alternatively you can use the latest svn version (though be aware that
I'm currently shuffling lots of code around in svn).

Let me know if it still doesn't work.
