[PyQt] Bye bye segmentation fault

[Cyril Giraudon]

  Hello,

I am a PyQt newbye and I wanted to do some tests with QToolBar in a 
QDialog (Seems multiple QMainWindow use is not recommanded in a 
QApplication), so I started coding a simple example (reported below).

The code seems correct but it terminates with a segmentation fault when 
the QUIT button is pressed :

"""""""""""""""""""""""""""""""""""""
(sandbox)cyril at CGN-L: pyqt$ python example.py
Qt version :  4.6.2
PyQt version :  4.7.2
Erreur de segmentation
"""""""""""""""""""""""""""""""""""""

I don't understand what happens.
Is there any explanation ?

Thanks a lot,

Cyril.
