Summary: Crash if getvar of a non-existent Tcl variable

Initial Comment:
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.

to apply it).
