FWIW, I've worked this around and successfully loaded the expectation file 
after making the following change:

--- qm/test/context.py  10 Jul 2003 00:33:02 -0000      1.11
+++ qm/test/context.py  15 Jul 2003 05:32:13 -0000

+    __safe_for_unpickling__ = 1

     def __init__(self, context = None):
         """Construct a new context.


OTOH, I have no idea
- why it's necessary
- why Result class is readed OK, but Context is not.

Can anybody shed any light on this?
