Yes. Including that file in zcml solved the issue.

        <include package="zope.app.security" file="_protections.zcml" />
Apart from the PersistentList and PersistentDict I see many other BTree
related allow attributes configurations. I guess these configurations
are not available in any other place and including this
'_protections.zcml' is safe.

Thanks for the tip.
