Let's see whether I got it right: someone noticed that MtGOX made a tiny transaction, which actually was like several others that they had been doing all along since the lock-in; a transaction which had nothing to do with withdrawals, and moreover was rejected by the network because it contained mined bitcoin that was too fresh -- a bug that MtGOX's software was known to have, and which apparently has not been fixed yet.  That is why the market suddenly got excited and optimistic, and the price jumped up by 10% in a few hours . Correct?
