regression: firefox 8 HTML5 audio: audio element does not report duration for audio data uris

[Tal Shalif]

Printing player.currentTime, player.duration from the timeupdate event callback produces the following on Firefox 8:

onTimeUpdate: 0.029433 / Infinity
onTimeUpdate: 0.296326 / Infinity
(lines skipped)
onTimeUpdate: 6.724444 / Infinity
onTimeUpdate: 7.325759 / Infinity
onTimeUpdate: 7.325759 / 7.325759
onEnd: 7.325759

But on Firefox 7.0.1+build1+nobinonly-0ubuntu2 duration is correctly reported:

onTimeUpdate: 0.02839 / 7.325759
onTimeUpdate: 0.298276 / 7.325759
(lines skipped)
onTimeUpdate: 7.321451 / 7.325759
onTimeUpdate: 7.325759 / 7.325759
onEnd: 7.325759
