Oh, man. Why did you send the 1? Were you just testing to see how the backup worked? Why with so many coins?
That sucks.
Actually, the sad part was I wasn't even testing the wallet backup when this happened. I was trying to watch when the network should have confirmed a payment to a website that takes bitcoins by paying myself 1 coin at about the same time. I never dreamed it could compromise my whole balance, especially since I was sending to myself.
Ugh, that's awful.
