[Brian Smith (:briansmith, :bsmith, use NEEDINFO?)]

Probably a dupe of bug 764171. Let's see if this occurs now that bug 764171 is fixed. On mozilla-inbound, the patch for bug 764171 landed in revision 1f695f10fa11, which was just a few hours after revision b4fdcc91afb9 landed, so we should never see this again.
