Missing to load app/model/Theme.js

I just try to update the demo application and the 'app/model/Theme.js' file exists but he isn't load:
http://mapfish-geoportal.demo-camptocamp.com/sbrunner-demo/wsgi/mobile_dev/#home

Then I have the error : 
``Uncaught Error: [ERROR][Ext.data.Store#setModel] Model with name "App.model.Theme" does not exist. ``
