[snip... about 30 or 40 lines around the offending one would have been
enough :-) ]

This is the access to

        ci->modes

in _vds_shared_init(). It looks like ci (= vi->codec_setup) isn't
properly initialized (by vorbisfile).

That's where I stop, I never used vorbisfile before. I guess something
didn't handle its error codes while reading the stream headers.

Cheers,
