[Zope] objectValues ques

[AM]

I have a dtml-tree method:

<dtml-let root="site">
  <dtml-tree name=root branches_expr="filter_tree_nodes()" nowrap single 
skip_unauthorized>
    <dtml-var id>
  </dtml-tree>
</dtml-let>

where site is a folder in my zope install
and a PyScript::

excl_list = 
['acl_users','errors','layout','site_admin','sql_methods','util']
obs = context.objectValues()
for ob in obs:
    if ob.getId() in excl_list:
        obs.remove(ob)
return obs


Now the strange part is that is 'site' were a LocalFS object this works 
fine.... but the moment 'site' is a folder in my Zope root, I get an 
Unauthorised  (Cannot access objectValues in this context) error,
even though I am logged in as manager.

Why does this happen??

The traceback:
