[Zope] Security on email.Message.Message

[Tim Hicks]

Hi,

I'm trying to import and use the email.Message.Message class in a zope
'Script (Python)'.

I have the following security assertions in my product code::

  from AccessControl import allow_module, allow_class
  from AccessControl import ModuleSecurityInfo

  ModuleSecurityInfo('email.Message').declarePublic('Message')
  from email.Message import Message
  allow_class(Message)

As a result, I can successfully import like::

  from email.Message import Message

I can even create an instance and call most methods on it::

  m = Message()
  m.set_payload('read that')

However, when I try to use the mapping interface, I get an error.  For
example, the following::

  m['from'] = 'tim at example.com'

produces a traceback like::

  Traceback (innermost last):
    Module ZPublisher.Publish, line 101, in publish
    Module ZPublisher.mapply, line 88, in mapply
    Module ZPublisher.Publish, line 39, in call_object
    Module Shared.DC.Scripts.Bindings, line 306, in __call__
    Module Shared.DC.Scripts.Bindings, line 343, in _bindAndExec
    Module Products.PythonScripts.PythonScript, line 323, in _exec
    Module None, line 6, in AAA
     - <PythonScript at /test/AAA>
     - Line 6
    Module RestrictedPython.Guards, line 96, in handler
  TypeError: object does not support item or slice assignment

Does anyone have any idea what the problem is?
