After creating debug versions of Python, Qt, PyQt and sip, I have found 
the bug. It is not in sip, it is in PyQt.
With PyQt-snapshot-20050630, you reimplemented the 
%ConvertToSubClassCode for all QObjects.
In PyQt-snapshot-20050704/sip/qt/qobject.sip starting at line 346 the 
value for the 'no' struct element must be 110 and not 111. An index 
value of 111 points to the data after the graph[] array. It depends on 
the current style and/or the current data after the array, if calling 
style() on a QApplication or QWidget instance crashes or goes into an 
endless loop or works without error.
