This has all the symptoms of some kind of memory error - unfortunately the symptoms are often not directly helpful in diagnosing the root the problem (since the memory error occurred sometime before the random insanity started...)
I'm not up on the implementation details of tcl/tk, but its not out of the question that it could interact badly with objects that come from PythonNet (which has to do some arguably evil things with object structs, etc.) If you can narrow it down to the simplest possible case and send me that script, I can try to help investigate...
