When you get errors, you should look at the traceback!

The traceback will tell you where (in the code) the exception
is raised.

I would catch the exception and analyse the content of the failing
attribute (to find out what precisely is not picklable).

Hi Dieter,

Thanks for the quick reply. I'm not a Python programmer but will keep
plugging away at it. In the meantime, maybe someone can make some quick
sense out of this traceback and give me a suggestion.

Thanks again.
Steve
