At the moment it causes failure of one of the unit tests
(zope.app.services.tests.test_zpt.Test.test_usage) and one of the
functional tests (...TestVirtualHosting.test_request_url):

  TypeError: issubclass() arg 1 must be a class

I added a debugging print there and found, that obj is a security
proxied dict {'template_usage': u'spam'}.  issubclass gets <type 'dict'>
as its first argument and barfs.
