Issue 802417: Bogus use of Tkinter.PhotoImage can give sig11 (original) (raw)

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 Starting program: /usr/local/bin/python tkinter-image-bug.py [New Thread 1074993152 (LWP 30584)]
