[Zope-dev] Experiencing TypeError: The object is not a PySECURITY_ATTRIBUTES object

[Chris Mattmann]

Hi Guys,

Thanks for your responses. I'll investigate the version of Plone that I had
downloaded (2.1.1) to see whether or not there are any calls to the
pywintypes32 library within the Plone products that could be causing this
problem. I had suspected it may be a Plone issue because I didn't see the
problem when I just installed Zope, and started it up. Only after adding the
Plone products did I start to see the problem. However, I wasn't sure what
might be causing it because I'm not really a Python guy. To be honest, I've
never used it before. So I'll check into this and get back to you. I'd be
happy to test the proposed solution BTW, if you send me a tarball, and
report the results to the list.

Thanks!

Cheers,
  Chris
