In 2.3, the code:

    from Tkinter import *
    x = Tk()
    x.getvar('foobar')

will crash.  This is due to bad error checking in 
_tkinter.c, in the GetVar() code.

A possible patch is attached.

Making p7 because it's a crasher.

The patch is fine; please apply (or reassign if you want me
to apply it).

Sorry, I'm afraid I'll have no time to apply before 2.3.1. -- if 
you do, please apply it.
