grenv: As far as I know there is no rule against doubling a dead cube. Since by definition it cannot give the doubling player an advantage, I don't see why there should be a rule against it. The only harm that I can see is that an inattentive player might drop, but rules are generally not imposed to protect players from their own sloppiness.
