win32com: get error 80004005 in attempt to use a pythom COM s erver - found it!

[LArbilla at pav.com]

I found the problems:
1) I had a field, _pid, in class RAE, which I meant as private.  However it
needed to be declared
in _public_attrs_.  Is there a _private_attrs_ declaration ?
2) Also, the line:
			self._pid = raeapimodule.ConfigFromFile(fileName)
needed to be changed to
			self._pid =
raeapimodule.ConfigFromFile(str(fileName))
to avoid an error converting between Unicode and Python strings.

FYI,
Laura.
