eth_getFilterLogs causes error

[frozeman]

If you create pending Transactions filter:

{jsonrpc: "2.0", method: "eth_newPendingTransactionFilter", params: [], id: 14180}

And then try to eth_getFilterLogs:

{jsonrpc: "2.0", method: "eth_getFilterLogs", params: ["0x2"], id: 14181}

The nodes spits out the following error:
