I've been using Coinbase.com and really liked them. No troubles, and really easy to use. I had setup two factor authentication, setup a safe password, use Noscript and Adblocker, and scan my computer all the time with AVG and Malwarebytes. So I sent 10.399 Bitcoin there to sell. The 6th confirmation hit, and the status on the transfer said it would be valid any minute. Yet when this happened, another order popped up to send the exact same amount of coins to an external address exactly one hour to the minute the orginal transaction to receive BTC was recognized. Both were clearly pending at the same time. I never even saw the money hit my account.
Here's "advanced details" page on the order to send the coins to an external account:
