I didn't get this problem, but I just finished reading the PTK source
(lucky me!).

Alter lib/python/Products/PTKBase/PortalCatalog.py, line 14, to read:

        self._catalog.addIndex('allowedRolesAndUsers', 'KeywordIndex')

instead of

        self._catalog.addIndex('_allowedRolesAndUsers', 'KeywordIndex')

change line 47 to

            kw['allowedRolesAndUsers'] = list(user.getRoles()) + \
instead of 
            kw['_allowedRolesAndUsers'] = list(user.getRoles()) + \


The other related line is in
lib/python/Products/PTKBase/PortalContent.py, line 45:

    def _allowedRolesAndUsers(self, permission='View'):
        """
        Return a list of roles and users with View permission.
        Used by PortalCatalog to filter out items you're not allowed to
see.
        """

you'll also need to change this method name to remove the underscore.


Watch out, though -- I have no idea what these changes do to the
security of your PTK site!
