[Pythonmac-SIG] Crash in MacPython 1.5.2c2 and Tk oddities

[Russell E Owen]

The following code (simplified from Grayson's "Python and Tkinter") 
reliably causes a crash into MacsBug on my 7200 running MacOS 8.6. I 
put it in a file and run it by dropping it on PythonInterpter.

Anybody else see this?

Also, as you probably know, Tk fails to exit properly in 
PythonInterpter when the quit command is issued or a window is 
closed. If I have python execute the quit method of the root window 
(which seems to be standard behavior for a quit button) or if I close 
the root window by pushing its close control, the interpreter ignores 
all requests to quit. and blinks as if it is processing events oddly. 
I find I have to do a forced exit.

The workaround for me is to always use cmd-Q or File:Quit to halt the 
Tk application, then wait until the interpreter output says the 
process has been killed (the Tk windows stay open, but are no longer 
active), then issue cmd-Q or File:Quit again to exit the interpreter.

P.S. I am sending this, with the output of StdLog after the crash 
directly to Jack Jansen.
