Message 76562 - Python tracker

Start IDLE, and hit Ctrl-N twice to create two windows named "Untitled":
This displays the message
"""
warning: callback failed in WindowList <class 'TypeError'> : unorderable 
types: ListedToplevel() < ListedToplevel()
"""
And the "Windows" menu does not contain the windows list.

This is specific to python 3: Windows objects cannot be ordered any 
more. Patch is attached.
