    Are these error codes still supposed to be working? I only get the 200 one, which is good in a way, but I was testing my error handling. And I tried to fill in an invalid API key, or just a random username, But all I get is a black screen, no json output with an error code?

    Hi there. In case of request to non-existent resource ( Klout returns HTTP status line with missing description ("HTTP/1.1 596"). Could you please fix that.
