It is likely that the object looks like a dictionary (it uses
a string representation like that of a true 'dict') but it is not
a proper dictionary (but rather some instance of a class).
Zope's restricted code treats proper dictionaries as unprotected
(like it does for lists and tuples) but requires special
security declarations for instances to be accessible in untrusted
A solution for you might be to convert the RSS data into
a proper dictionary. How this works in detail depends
on the instance at hand. If it implementes an "items" method,
then "dict(instance.items())" would do it.
Note that substructures, too, may look like Python types
but are in fact instances. In this case, you would need
to convert such substructures as well (similar to the
top level object).
