BadValueError when trying to create new object that contains referenced property

Creating a new comment from the sample classes (in QuickStart wiki page),
edit referenceproperty.
'reference' fails appengine_admin\__init__.py", line 76, in _attachListFields

   property.value = getattr(item, property.name)
 File "C:\Program\Google\google_appengine\google\appengine\ext\db\__init__.py",
line 2421, in __get__
   raise Error('ReferenceProperty failed to be resolved')
Error: ReferenceProperty failed to be resolved

I run the Article and Comment classes and "create new comment" results in
http://localhost:8080/admin/Comment/new/
appengine_admin\__init__.py", line 139, in get
   self._callHandlingMethod(url, self.getRegexps)
