getInheritedLocalRoles in PloneTool fails with "AttributeError: acl_users"

[partecs]

I have a catalog index which calls computeRoleMap(). This in turn calls getInheriredLocalRoles() which fails on the following line:

        if portal != here:
            parent = here.aq_parent
            while cont:
!!!=>           userroles = parent.acl_users.getLocalRolesForDisplay(parent)
                for user, roles, role_type, name in userroles:
                    # Find user in result

Seems that parent has lost its acquisition underwear somewhere!

So I made a small change:

        if portal != here:
            parent = here.aq_parent
            while cont:
+++ FIX         if not getattr(parent, 'acl_users', None):
+++ FIX              break
                userroles = parent.acl_users.getLocalRolesForDisplay(parent)
                for user, roles, role_type, name in userroles:
                    # Find user in result

Now all is well!

Sorry... I should have done a page preview:

(In [10385]) Made getInheritedLocalRoles in PloneTool more error resilient. This closes #5542.
