Paolo, can you have a look at this failure?
I'm not sure if I'm using OrangeFactor correctly, but this failed, like... two times? This is the check that fails, it's inside a pretty straightforward test that doesn't do much: do_check_true(destFile.equals(aTarget)); The destFile variable is an nsIFile pointing to a file in the temporary directory, from code inspection I don't think aTarget can ever be null, and we never rename the target in this test. If I'm correct, until now this only failed on Windows XP, and the only thing that comes to my mind is that maybe for some reason GetShortPathNameW from the nsLocalFileWin implementation gave inconsistent results.
