Warning: Possible EventEmitter memory leak detected - node.js

Question

I'm getting an error doing a very basic GET request using the request module.
Here's my code:
var request = require('request');
var url = 'http://www.bigassfans.com/case-studies/delphine-restaurant/';
request({
url : url,
headers: {
'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.94 Safari/537.36'
}
}, function(error, response, html){
console.log(response.statusCode);
console.log(response.headers);
});
Here's my error messages:
(node:75952) Warning: Possible EventEmitter memory leak detected. 11 pipe listeners added. Use emitter.setMaxListeners() to increase limit

What's going on? Is this a bug in the request module or is something wrong with my code?
