Throwing it into the commit queue just to see what happens; marking it cq-, though, as I can't see why this patch would cause crashes.

[Mike West]

Ok, this isn't your fault. Things have been crashing on Chromium for a day or so, Garden-O-Matic just relisted them and confused me. :( Closing this bug, will file another soonish.
