[PyQt] sip.pyd crash due to class order of inheritance

[Demetrius Cassidy]

import sys
from PyQt4 import QtCore, QtGui

app = QtGui.QApplication(sys.argv)

class Ui_Frame(object):
    def setupUi(self, Frame):
        Frame.setObjectName("Frame")
        Frame.resize(200, 300)
        Frame.setMinimumSize(QtCore.QSize(200, 200))

class FrameWnd(Ui_Frame, QtGui.QFrame):
    
    def __init__(self):
        QtGui.QFrame.__init__(self)
        self.setupUi(self)
        
frm = FrameWnd()
frm.show()
sys.exit(app.exec_())

If you inherit from Ui_Frame before QFrame, you get a crash in sip.pyd. But
if you swap the order around it works fine. This is using  Sip 4.10 12/23
snapshot along with PyQt 4.7 12/23 snapshot
