I am starting with Ember and just following this tutorial. I downloaded the last source from Ember.js web and I have the following code:

HTML

<!doctype html>
<html>
 <head>
   <script src="js/libs/jquery-1.7.2.min.js"></script>
   <script src="js/libs/ember-1.0.0-pre.2.min.js"></script>
   <script src="js/libs/handlebars-1.0.0.beta.6.js"></script>
   <script src="js/app.js"></script>
 </head>
 <script type="text/x-handlebars" data-template-name="application">
   Test
 </script>
</html>

app.js

   App = Em.Application.create();

   App.ApplicationView = Em.View.extend({
     templateName: 'application'
   });
   App.ApplicationController = Em.Controller.extend();


   App.Router = Em.Router.extend({
    root: Em.Route.extend({
      index: Em.Route.extend({
        route: '/'
      })
    })
  });

  App.initialize();

It seems a pretty simple example, but I fail to see these two things:

1) Why the source of ember gives me this error: 

Uncaught TypeError: Object prototype may only be an Object or null

On line 18 of the ember code.

2) Why I keep getting this uncaught error, if I have defined the template:

Uncaught Error: <App.ApplicationView:ember143> - Unable to find template "application".

Reset to default 5

Try putting the application template before handlebars.

<!doctype html>
<html>
 <head>
   <script type="text/x-handlebars" data-template-name="application">
     Test
   </script>
   <script src="js/libs/jquery-1.7.2.min.js"></script>
   <script src="js/libs/handlebars-1.0.0.beta.6.js"></script>
   <script src="js/libs/ember-1.0.0-pre.2.min.js"></script>
   <script src="js/app.js"></script>
 </head>
</html>
