I am unable to run even a simple application using PySide under Windows XP SP2
using the Python interpreter. Actually, there is no GUI appearing and the
command line hangs when I execute the application. I am not even able to press
Ctrl-C to break the execution.

On the other hand, if I use py2exe, my application runs fine. But of course,
this makes development a lot more tedious.

I am using Python 2.7 with PySide 0.4.2.

Here is the output produced when I try to run t1.py from
pyside-examples/examples/tutorial:
