Problems:
1. Not compatible with the bitcoind JSON-RPC API. getaccountaddress(account) where account is a new one creates that account in bitcoind, in Blockchain.info it just returns an error.
2. Cryptic error messages. I am calling listrecievedbyaddress() and I get:
"Array ( [error] => Array ( [message] => [c.ode] => -32603 ) [jsonrpc] => 2.0 ) "
What is error -32603
3. Doesn't list transactions. For some reason, listtransactions() does not list my transactions, even through I can see it in blockchain.info..
