http://tinderbox.mozilla.org/showlog.cgi?log=Firefox/1296304882.1296305518.5816.gz Rev3 Fedora 12x64 mozilla-central opt test reftest on 2011/01/29 04:41:22 Reftest failure log attached.
Looked into this a bit, since this is my test that's failing. I can reproduce this failure reliably by moving this reftest to a remote SSH server, which I mount in a local directory via SSHFS. (This is a hack to make files load slowly.) I'm pretty sure this is what's causing the failure fail: (1) we finish reading the bits of the SVG file --> VectorImage tells host document "ready to paint!", in VectorImage::OnStopRequest --> BUT we haven't necessarily gotten all the bits of the stylesheet yet! (2) Document tells image to paint itself (3) Image paints as blank, since the stylesheet still being loaded. I think we'd really like to delay the VectorImage's "ready to paint!" notification (and hence the <img>/<body> load events) until the <svg> element fires 'SVGLoad' (which I think would happen after the stylesheet is ready (?)). HOWEVER, this is pretty low-priority and unlikely to cause problems in the wild. Given bug 628747, this bug only affects local SVG images that reference local stylesheets, since HTTP-served SVG images aren't allowed to reference external stylesheets at all now. I'm going to mark the non-HTTP version of this test as random, to stop the pain that its frequent orange causes, and I or someone else can fix the actual bug when time permits.

I suspect (though have not yet confirmed) that this may be fixed by bug 704059.
