I just upgraded my desktop from stable/stretch to testing/buster.
I'd earlier done the same to a laptop without any problems.
On the desktop, I get the following strange traceback :

I've tried reinstalling python3.7 and its library packages
without effect.

Any hints on how I might find what's causing this pathological
behavior?  TIA!

Don't have a solution for you, just a data point:

kent@westk-9463:~$ python3
Python 3.7.2+ (default, Feb  2 2019, 14:31:48)

Welcome to Python 3.7's help utility!

If this is your first time using Python, you should definitely check out
the tutorial on the Internet at https://docs.python.org/3.7/tutorial/.

Enter the name of any module, keyword, or topic to get help on writing
Python programs and using Python modules.  To quit this help utility and
return to the interpreter, just type "quit".

To get a list of available modules, keywords, symbols, or topics, type
"modules", "keywords", "symbols", or "topics".  Each module also comes
with a one-line summary of what it does; to list the modules whose name
or summary contain a given string such as "spam", type "modules spam".
