This issue was fixed now. Test on puddle 2.2/2015-06-25.1.
#rhc app create django python-3.3 --from-code https://github.com/openshift/django-example
The app could be created and could be accessed.
No errors during creation and app log.
According to https://bugzilla.redhat.com/show_bug.cgi?id=1265112#c3, the django app was created as an empty Django application, so it's normal the app url returns such prompt.
And there's no error during build and deployment steps, so move this bug as verified.
