The following program reliably crashes python.exe (2.3
RC1) on Win XP - SP1:


import Tkinter
tk = Tkinter.Tk()
quit_btn = Tkinter.Button(tk, text='quit', 
                          #command=tk.quit)  # This crashes
                          command=tk.destroy)  # This works
       
quit_btn.pack()
Tkinter.mainloop()


The error message is something like (bad english
translation):
The instruction in "0x77f4b2ab" points to "0x00000028".
The memory can't be read.

Were you using IDLE at the time?

When I try this (Windows XP SP2), the button and its window do not go away 
(which is arguably a bug), but it does not crash.

If I then try to close the window using the little X (from the window 
manager),

    (1)  A qb started from the command-line interface exits, as it should.
    (2)  A qb started from within IDLE becomes non-responsive, and Windows 
asks whether or not I want to continue shutting it down.

I've tried reproducing this on Windows XP using both Python 2.3.5 and
2.2.3 (and also some newer ones) and couldn't duplicate the issue. I
also tested the file attached on issue837234 and got nothing, changed it
a bit and still got nothing.

I can reproduce the IDLE freeze, but that is a different problem.

Closing this as rejected for lack of information.
