That's an infra problem, and should ideally be recognized as "status: exception" (purple) rather than busted/red.

Comment 1

[Phil Ringnalda (:philor)]

That does know that it's an infra problem (and a problem that follows some other problem): see, e.g., the purple http://tinderbox.mozilla.org/showlog.cgi?log=Mozilla-Aurora/1308965272.1308965392.21163.gz

The actual problem in your log was one buildstep above that, bug 660480, which does already know that it's the wrong color.
