This is something I had noticed some time ago...

[Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.9.2a1pre) Gecko/20090211 SeaMonkey/2.0a3pre] (experimental/_m-c_, home, optim default) (W2Ksp4)

27248 ERROR TEST-UNEXPECTED-FAIL | /tests/content/media/video/test/test_duration1.html | Check duration of video: 3.865999937057495
}

This occurs (the first time only ?) when I run the mochitest suite.
Afair, I tried to reproduce by running this test individually, but it passed.

The expected result seems to be 3.833...:
{
20   ok(Math.round(v.duration*1000) == 3833, "Check duration of video: " + v.duration);
}

This is a regression then.

I confirm that I can't reproduce by running only this test or only its whole directory.
I think I didn't try to run the whole tests suite again.

Yet, I think I saw this bug recently on some tinderbox !?

If so then it could be:
http://hg.mozilla.org/mozilla-central/pushloghtml?startdate=2009-02-10+14%3A06%3A13&enddate=2009-02-11+08%3A48%3A02
and maybe one of bug 469272, bug 476811 or bug 476176.

Probably 469272. I'm not really sure

Afair, I have not seen this again since my 20090316 build.
