I was looking at this more, and from my understanding, the turtle code is
continuing to run even when the TK window is destroyed. Thus the crash.
It looks like the drawing functions are being made on the fly with the
following method:
for methodname in _tg_turtle_functions:
pl1, pl2 = getmethparlist(eval('Turtle.' + methodname))
if pl1 == "":
print(">>>>>>", pl1, pl2)
continue
defstr = ("def %(key)s%(pl1)s: return _getpen().%(key)s%(pl2)s" %
{'key':methodname, 'pl1':pl1, 'pl2':pl2})
exec(defstr)
eval(methodname).__doc__ =
_turtle_docrevise(eval('Turtle.'+methodname).__doc__)
So while all the methods are being generated, I am going to add in a check to
see if the window was destroyed before running the pen code. If it was, then I
exit gratefully. The check will be duplicated for each pen method, but I feel
it is the best way to contain the check within the turtle.py module. The other
option would be to make the user check for it, which is not a good option.
