getreceivedbyaddress and mined coins

[spiccioli]

Hi,

I see that a json-rpc call to bicoind with method getreceivedbyaddress does not return mined coins which have that address as payment address.

I have several payment to such address from mining with p2pool.

Is there a call which returns mined coins or do I have to take the balance of all accounts inside wallet, subtract them from wallet balance and the result is mined coins?

TIA
