[Zope] manage_access problems

[Mario Olimpio de Menezes]

Hi,

	I'm having a strange problem with my Zope installation I need
some help to solve.
	When I try to access the security (manage_access) page of my
root Zope, I get the error listed below:

<!--
Traceback (innermost last):

	This only happen with root folder; in subfolders I can manage
security without problem, that is, I can access the page and add/remove
privileges, local roles, etc, even though I do not master it completely,
but this is another story.
	Any help?
	My zope configuration is:

Debian/GNU Linux 2.2 (potato)
zope 2.2.1
zope-guf 1.1.0
zope-pygresqlda 0.3rjr2
zope-renderable 0.2
zope-tinytable 0b2
zope-worldpilot 1.0.4
