Python TKInter bringing down xorg server

Berkelery's AI course on edX has a project to implement a search algorithm for a pacman style game which uses python 2.7 and TkInter.
When I try to run the graphical program it brings down KDE, Kwin, kdm and X11 too.
No error message, no warning, I am just dumped to a console.
Interestingly kdm eventually restarts by itself though.

The source code for the project

Here is a sample command that causes the situation

$ python2 pacman.py -l tinyMaze -p SearchAgent -a fn=tinyMazeSearch

If I try to run the program interacticveley it also blows up

$ python2 pacman.py

The relevant part of the system log:

$ jounralctl -b

I have 64bit installation using KDE 4.14.5.
All packages are up-to-date.

uname -srv
Linux 3.18.6-1-ARCH #1 SMP PREEMPT Sat Feb 7 08:44:05 CET 2015

Does anyone have any idea what can be causing this?
Or how to fix it?

Not a Programming issue, moving to Apps and DEs...
