Oh dear. It's there, yet not in the wallet.
My precious unconfirmed dividend

anyone a clue why it takes so long to confirm? has this happened any time before?
Simple. The transaction included 0.0001 in fees but the transaction size is 1481 bytes, which means not enough fees for the transaction size so it is waiting to be confirmed by a miner that accepts less than the normal minimum fees. Check it out on blockchain.info, click the transaction ID and look around, you'll see it is in a queue.
