FUD. Tried it for myself. Withdrawl from gox took less then a minute.
Apparently it's random. Smaller withdrawals have a higher probability of working than larger ones.
No real explanation so far as to what is causing the problem.
So 1.1 bitcoins is large? Its not related to amount, it's just luck of the draw when you try to make the withdrawal...if you are tangled up in the 'unconfirmed' freshly minted coins. It runs off Marks special PHP and SQL code.
