Unable to Load the app with ionic-angular2.0.0-beta.7

Hello, When I updated from ionic-angular2.0.0-beta.6 to 2.0.0-beta.7. I get this error : Cannot read property ‘registerBackButtonAction’ of undefined in app.js(line:31) on browser. i.e on node_modules/ionic-angular/components/app/app.js

I followed the steps given here: https://github.com/driftyco/ionic/blob/2.0/CHANGELOG.md#angular-update-to-200-rc1
