No, until that point the things in the Qt namespace and defined in QtGui 
hadn't been implemented in PyQt4 because it needed a SIP change to handle the 
split namespace.

The current SIP implements the split by putting a Qt in both QtCore and QtGui.

I have been persuaded to change the SIP implementation so that Qt only appears 
in QtCore and things get magically added to it when you import QtGui - 
precisely to avoid bug reports like yours. I might get this finished today.
