2.0b2: possible Tkinter bug

Transcript of a recent session.  Each time I ran testgraph(), I got my
sine wave in a Tk canvas.  After the 5th return to IDLE, I was starting
to type something else when:

 Python 2.0b2 (#6, Sep 26 2000, 14:59:21) [MSC 32 bit (Intel)] on win32
 Type "copyright", "credits" or "license" for more information.
 IDLE 0.6 -- press F1 for help
 >>> import tkgraph
 >>> tkgraph.testgraph()
 >>> tkgraph.testgraph()
 >>> tkgraph.testgraph()
 >>> tkgraph.testgraph()
 >>> tkgraph.testgraph()
 >>> Exception in Tkinter callback
 Traceback (most recent call last):
  File "G:\PYTHON20\lib\lib-tk\Tkinter.py", line 1287, in __call__
    return apply(self.func, args)
 SystemError: C:\Code\python\dist\src\Objects\frameobject.c:127: bad argument to
internal function
 Exception in Tkinter callback
 Traceback (most recent call last):
  File "G:\PYTHON20\lib\lib-tk\Tkinter.py", line 1287, in __call__
    return apply(self.func, args)
 SystemError: C:\Code\python\dist\src\Objects\frameobject.c:127: bad argument to
internal function
int(round(50))      <-- this was me typing
50
 >>>

Python crashes after.

Upon running again, I got a similar crash upon first run of testgraph().

If source code for my tkgraph module might be relevant, I'm happy to post
more.
