Request exceptions catched to prevent entering in a broken connection state

[ghost]

Sometimes, when you make a request, it can raise httplib Exceptions like BadStatusLine.
When this happens, the line to get the response is not called, and connection enter in a broken state.

If you make successive JSON calls, the object will always return "httplib.CannotSendRequest" error.

So, the connection is closed after the exception raised to prevent this kind of behavior.
