It seems like you code against a specific sub-type and not the parent class Guzzle\Common\Exception\RuntimeException as the method getResponse() does only exist in the following sub-classes of Guzzle\Common\Exception\RuntimeException: Guzzle\Http\Exception\BadResponseException, Guzzle\Http\Exception\ClientErrorResponseException, Guzzle\Http\Exception\ServerErrorResponseException, Guzzle\Http\Exception\TooManyRedirectsException. Maybe you want to instanceof check for one of these explicitly?
