Comment 8 for bug 226801

In case anyone is still encountering this problem, I've also recently run into it. I still haven't determined what causes the problem, but my guess would be it chooses some unusual plugin that can decode mp3 but can't handle seeking, rather than a more common one that can do both. I've specifically noticed, it seems only to do it to some mp3 files (those that file identifies as 'RIFF (little-endian) data, WAVE audio, MPEG Layer 3'). File incorrectly identifies a lot of my other mp3s as data or correctly as 'Audio File ... with MP3 encoding', and these totem doesn't seem to have a problem with. I hope that helps in some way...
