[PyQt] PyQt application crashes on exit

[Romi Agar]

Hi!

After upgrading my PyQt to version 4.7.2 on my windows 7 x64 machine running
Python 2.6.5 many of my applications tend to crash on exit. Python.exe stops
responding if I close the application window.
A simple example that seems to always crash on my pc is included as an
attachment.

Any ideas about how to fix it?

Thanks  in advance
