Segmentation fault (core dumped)
Is this a PyQt bug? a Qt bug? or most probably my bug?
Before the crash I get this message:
QFontDatabase::load: Must construct QApplication first
which means that my version of Qt has debug messages activated. You
might want to look into this.
The segfault has this traceback:

So it looks like it has nothing to do with PyQt. You may want to report
this to the Trolltech guys.
