Summary: Bogus use of Tkinter.PhotoImage can give sig11

Initial Comment:
Running the following script can cause a signal11 (the

script is invalid, but presumably should result only in

a traceback, not a sig11):

from Tkinter import *

t = Tk()

i = PhotoImage(t)

print "here"

The signal 11 happens before the print statement is

reached.

My system is RedHat9, tcl/tk 8.3.5, Python 2.2.2 (also

observed on 2.3b1)

This may be a tk bug (thus unfixable in

Python/Tkinter), because the following sequence kills wish:

% image create photo . 

Illegal instruction

The traceback looks like this:

(gdb) run tkinter-image-bug.py
