[Zope] aq_explicit permission: where set?

Your advice was quite helpful. Now I got this:

Error Type: Unauthorized
Error Value: The container has no security assertions. Access to 
'aq_explicit' of (BrowserIdManager instance at 89285e0) denied.

Here's the offending piece of Python Script:

def isAFolder(obj):
   return hasattr(obj.aq_explicit, 'isPrincipiaFolderish')


It look like browser_id_manager will not allow me to question whether it 
is folderish. This looks silly. What permission should I check to find 
out which objects refuse to divulge this info?
