Sorry, my bad.

@Renerick Thanks for the report :) I've moved the issue.

While the Ruby demo silently renders the fragments instead of the whole page when you use the back button, the Django demo allows you to go back one page, but then it crashes (I know it's a different project, but just highlighting a similar problem)
