[Zope] Proxy role + zclass + python script = Unauthorized

[Ayhan Ergul]

Folks,

I have a python script (called "clone") defined as a
method of a zclass that, when invoked on the instance
of the zclass (KM Chart Applet), makes a copy of the
instance in a different folder. This works fine when
the user has role manager, but fails with
"Unauthorized" complaining about the permission "Add
KM Chart Applets" although the script has proxy role
manager.

In the python script manage_copyObjects succeeds but
manage_pasteObjects fails (traceback below). Running
zope 2.3.3

Any clues why I'm losing the permission when running
the script proxied to manager as opposed to a user
with manager role? I don't think I'm running into the
post 2.2 policy of not propagating proxy roles, since
the python script is called directly from browser and
it calls the stock manage_....Objects() directly??
