malformed json response

[dreadjr]

When carrot returns a body that cannot be parsed by JSON.parse, there is a try/catch but the catch doesn't return the callback(), so the code continues and crashes.

res.on('end', function() {
152 try {
153 var output = JSON.parse(body);
154 } catch(err) {
155 callback("Malformed JSON response.", search_result);
156 }
