Well right now we don't fail gracefully and i don't think we should unless
we are dealing with something introduced in later versions that doesn't hurt
or to generate helpfull error messages that explicitly tell you what new
stuff the serialized data contains the old version being runned cannot deal
with (e.g. Unicode data).
