I ran into issue with listunspent API call.
getaddressesbyaccount("account") returns ['n1az1tf4FozhBRVG7Ab43e2iLGPPBasXbe'] - my account has only 1 address.
I call getbalance("account", 6), I get a value of 2203.46345285 - I have 2K testnet Bitcoins in that address, that looks like a plenty of transactions to spent.
I call listunspent(1, 999999, ["n1az1tf4FozhBRVG7Ab43e2iLGPPBasXbe"]) and get [] - nothing.
I did not use "move" command, just a lot of non-standard calls for creating new transactions and sending them (createraw, signraw, sendraw).
I check BTCLook and see plenty of unspent transactions - http://testnet.btclook.com/addr/n1az1tf4FozhBRVG7Ab43e2iLGPPBasXbe .
Similarly, calling listtransactions("Holding", 10, 0) returns:

This is why I think that there is some bug in listunspent that makes this API call not return proper values.
