Decoding some old Vorbis encodes fails

[Case]

Summary of the bug:
FFmpeg decoding fails with certain Ogg Vorbis files. The file has some granulepos problems as reported by ogginfo tool, but even after fixing them with revorb (a stream rewriting program) the decoding still fails. Official oggdec tool has no problems with the sample before or after the stream rewrite.

How to reproduce:
I uploaded a sample file with name vorbis_fails_to_decode.ogg to the FTP server.

% ffmpeg -v 9 -loglevel 99 -i vorbis_fails_to_decode.ogg out.wav

Sorry, this is a defect. It fails with valid ogg vorbis files.
