ComputedAttributes sometimes run afoul in the permission machinery with the following sort of error (courtesy VerboseSecurity):

"""
Module Products.PageTemplates.Expressions, line 336, in restrictedTraverse
   - __traceback_info__: {'path': ['cgpublisher_url'], 'TraversalRequestNameStack': [], 'page_layout': <CG TemplatedHTML page_layout at 0x3b5de00>}
  Module AccessControl.ImplPython, line 404, in validate
  Module Products.VerboseSecurity.VerboseSecurityPolicy, line 101, in validate
Unauthorized: No container provided.  Access to 'cgpublisher_url' of None, acquired through (CG WebSpace web at 0x3b5d9c0), denied.
"""

Where "cgpublisher_url" is the ComputedAttribute.
