To all,

I've been using SpamBayes for some time on Window 2003 Server.  After
upgrading to Windows 2003, the plugin no longer works.  After some
debugging, It was determined it was probably a PyWin32 problem.

Python 2.4.1

I have tested the example Outlook plugin
(win32com/demos/Outlookadin.py).  That plugin also crashes Outlook.  I
added a bunch of win32traceutil;print statements to attempt to figure
out where the crash it.

The output I get is this:
