Tkinter-related problem

[Robert Vollmert]

Hello,

does anybody know what might be causing the following errors? Could
they be caused by python code or the Tkinter module, or should I
rather search elsewhere? They occur while running a Tkinter program
(redhat linux 6.0, tk 8.0.4-29, tkinter/python 1.5.1-10). The same
program runs without error on my system (debian 2.1, tk 8.0.4-2,
python/tkinter 1.5.2).

As I can't reproduce the error locally, I don't know what code is
causing this exactly. The program is an application launcher for the
dock of WindowMaker (a window manager). It is available at
    http://home.t-online.de/home/robert.vollmert/wmlaunch.tgz
in case anybody is interested in it.

Thanks,
Robert
