As far as I know a key logger can't be the problem, because I used the Two-channel auto-type obfuscation that KeePass offers.

that was the remaining amount of bitcoins left in my wallet. I wanted to send them to my Mt.Gox account. But in a hurry I forgot they used one address per transaction so I never received it.
No I don't often check my balance, since I assumed it was safe. And I'm not a active BTC user, it was just a savings account.
As far as I am aware of, I'm the only person with access to my server. I download my torrents from a private tracker and I never said a word about bitcoins in that community.
My nickname is about 9 years old. I was a fat kid and walked like a penguin (my friends thought so). Thus the nickname Linuxxl. I never used Linux until last month, for creating a bootable USB stick to store my new wallet.
I understand your scepticism but I can assure you I'm not trolling or whatever. If you have doubts about my story feel free to ask any questions. Preferably before you start judging.
