The last two transactions are a double-spend. Blockchain.info hasn't gotten around to dropping the unconfirmed one for some reason.
FYI, the correct term is "address", not "account". An account is what you have at Coinbase, though some wallets also have a feature that allows you to separate the wallet into different "accounts".
Thank you very much. Yes, I am aware of the term, but it happens to me to use account instead of address sometimes.
Double spend does explain the issues. I was wondering why the second spend has not been confirmed for such a long time. Double spent clears it up.
