Unconfirmed transaction
The transaction doesn't seem to have propagated through the network, meaning that not many nodes know about it.  I personally am not sure what to do about that, if there is anything you can do about it.  

You could try having the person who sent you the coins restore their wallet from a backup, rescan the blockchain, and send you the coins again.  I think you might be able to get them through like that.  I would recommend having them put a transaction fee on it, though.  That should help it get put into a block quickly.
