Waveforms not in sync with audio (but only for ogg)

Bug Description

I was looking at why the played audio doesn't quite seem to match up with the waveforms. I wrote a short script to generate a small ogg file with test tones starting at exact second intervals. I checked it in audacity (first screenshot). I then loaded it into jokosher (second screenshot). Note that in jokosher the waveforms start to get out of sync with the second marks in the timeline. Curiously if you convert the ogg file to mp3 then it displays correctly. The third screenshot shows the mp3 and ogg together. Another very odd thing - I can't get the jokosher to play the ogg without it splutering and dying after about 3 tones.

After some testing tonight, it seems to mainly only affect Ogg files, as mentioned. This suggests it could be something with the GStreamer Ogg decoder. Maybe it is not reporting accurate levels when building the waveform - the fact it works with MP3 and WAV suggests it is not a Jokosher bug.
