Section of code causing error:

       from django.core.urlresolvers import resolve
        view_func, args, kwargs = resolve(request.META['PATH_INFO'])

         if hasattr(view_func,'view_func'):
            # it the view_func has a view_func then its a decorator
            co = view_func.view_func.func_code
        else:
            co = view_func.func_code   <---- fails here

Your code relied on the implementation of the user_passes_test decorator - in particular the _CheckLogin object, which is why it has broken, because that implementation has changed.

In your case, it looks like you are assuming that if the callable does not have an attribute 'view_func', then it is a function. That is an obviously false assumption.
