title: Meteor - Many errors after update to v0.9.1
body: <p>I've been working on a Meteor project for a month then yesterday I was asked to update to the Meteor v0.9.1 version. After that, when I start my app using <code>meteor</code>, it throws a lot of error on the client-side console. Here they are:</p>
