[Tutor] Unpickling problem

[Phil Bertram]

Hi all,

I have some code in a module named NPCObjects, describing 'Players',
'Matches' and collections of them. This code works fine in command line
mode. However I am trying to write a user interface using Tkinter.
When try to contruct my NPC object from a menu in Tkinter I get the
following error.
Note that the __init__ method of my NPC object unpickles a file to create
the object.

What is going wrong ?

Traceback (most recent call last):
  File "C:\Program Files\Python20\Pythonwin\pywin\framework\scriptutils.py",
