Go with the default error message used by BaseHTTPServer.BaseHTTPRequestHandler.send_error rather than the one thrown by socket.error which, I think, is some kind of object which, when passed to send_error, results in another exception.
Exception happened during processing of request from ('127.0.0.1', 35444)
