How can I use namespaces?

This crashes:

  <script>
    var App = {};
    $(function() {
      App.Detail = Backbone.RelationalModel.extend({});  
      App.Master = Backbone.RelationalModel.extend({
          relations: [{
              type: Backbone.HasMany,
              key: 'details',
              relatedModel: 'App.Detail',
              reverseRelation: {
                  key: 'master'
              }
          }]
      });

      var master = new App.Master;
      var detail = new App.Detail;
      master.get('details').push(detail);
    });
  </script>

Seems to be an issue with using underscore.js 1.4.0 (1.3.3 works fine)

I'm having the same problem, but 1.3.3 didn't fix it for me (I didn't check if I needed to downgrade backbone as well.)

I'm also using another level in my namespace:

App = {
  Models: {},
  Collections: {},
  Controllers: {}
}

Seems to work fine with latest Underscore, Backbone and Backbone-relational.
