Summary: Segmentation fault while using Tkinter

Initial Comment:
While using Tkinter I encountere segmentation faults
regularly. I ran my program using gdb using python2.4
and Fedora Core 5 and received:

I ran the same program using python2.5a2 and again
received:

Are these information enough for fixing the problem or
should I send my program?

Thanks

If you can send a small test case that would be great. 
Also, can you attach the backtrace (bt command in gdb)?

How did you configure python?  Did you use an
--enable-unicode or --enable-threads?  Did you built Tcl/Tk
or are you using the default version with FC5?

When python starts up, what do you see?  It should be
something like:

Python 2.5a2 (trunk:45831M, Apr 30 2006, 23:27:02) 
[GCC 4.0.0 20041026 (Apple Computer, Inc. build 4061)] on darwin


Also, what does this print:  
    import sys ; print sys.maxunicode

Please do send your program, or better yet a small test case
that allows to reproduce the problem. It looks like a Tk bug
at first glance, in TkUndoSetDepth.
