I have this as well, on Firefox 3.5.3 under both Windows 2000 and Windows Vista.
I have an application that makes an XMLHttpRequest every 5 seconds. The page alternates between waiting for the 5-second timer callback and waiting for the XMLHttpRequest callback. When I leave the page by clicking on an image, the XMLHttpRequest callback is sometimes called with state=4, status=0.

The changeset at "http://hg.mozilla.org/mozilla-central/rev/151522b6da28" looks like it explains this situation.
