More tkinter Madness

[Tim Daneliuk]

I am the author of twander (https://www.tundraware.com/Software/twander).
This code has run flawlessly for years on FreeBSD, Linux, MacOS and
Windows.  Some months ago, I put it on a couple of VPS servers (FreeBSD
and Linux) and BOOM, it doesn't run.  I asked around here and got some
suggestions and then did some homework.

I see the error being thrown by using the trace module, but it's not 
terribly meaningful to me.  Any ideas of what this means - again,
I emphasize this is only happening on VPS hosts:
