MtGox finally accepted my bank account. Pushed some PLN to my bank. We'll see. It is rather low amount (less than 0.2 BTC). Will keep you informed.
Is this a general pattern - a few small withdrawals go though, but not big ones? That's yet another indication that Mt. Gox is out of money.
No, the amounts I received through SEPA are all large (>> 1k) and they go through as stated in their FAQ.
