I know who wrote the line you fixed now. But strangely, it is quite old:

$ svn blame libmpdemux/demux_ogg.c|grep -C 5 ">context)->vi.rate"
 11576       mosu   if(demuxer->video->id >= 0) {
 11576       mosu     os = &ogg_d->subs[demuxer->video->id];
 11576       mosu     rate = os->samplerate;
 11576       mosu   } else {
 11576       mosu     os = &ogg_d->subs[demuxer->audio->id];
 11576       mosu     rate =
(float)((ov_struct_t*)((sh_audio_t*)demuxer->audio->sh)->context)->vi.rate;
 11576       mosu   }
 11576       mosu
 11576       mosu
 11576       mosu     switch(cmd) {
 11576       mosu       case DEMUXER_CTRL_GET_TIME_LENGTH:

(this was on r18739 of course)

$ svn log -r 11576

Get the total length for Ogg files. Patch by Michael Behrisch
<behrisch at informatik.hu-berlin.de>.

(also see: svn diff -r 11468:11576 libmpdemux/demux_ogg.c)

Maybe something else in that context broke it (not being able to play
ogg files couldn't hide for more than 2 years?!). But I thought you
might be interested in that info..

PS: I just checked on the pre8 branch and it plays the file fine..
