[PyKDE] Problem (re)connecting QWizard buttons

[Ulrich Berning]

Look at the following code:

(Yes, I know that reimplementing accept() is the better way)

---8<---------------------->8---
import sys
from qt import *

class MyWizard(QWizard):
     def __init__(self,parent=None,name="",modal=False,fl=0):
         QWizard.__init__(self,parent,name,modal,fl)

         # Disconnect the default slot
         self.disconnect(self.finishButton(),
                         SIGNAL('clicked()'),
                         self, SLOT('accept()'))

         # With the lastest sip/PyQt snapshots,
         # this additional reference is necessary
         # *before* we connect to our own slot
         # ---
         # With sip-4.2.1/PyQt-3.14.1, this
         # additional reference wasn't necessaray.
         # Is this a bug or an intentional change?
         self.fb = self.finishButton()

         # Connect to our own slot
         self.connect(self.finishButton(),
                      SIGNAL('clicked()'),
                      self.myFinishSlot)

     def myFinishSlot(self):
         print "myFinishSlot()"
         self.accept()

if __name__ == "__main__":
     a = QApplication(sys.argv)
     QObject.connect(a, SIGNAL("lastWindowClosed()"),
                     a, SLOT("quit()"))
     w = MyWizard()
     w.show()
     a.exec_loop()
---8<---------------------->8---

With the latest sip/PyQt snapshots, I have to store an additional 
reference to the finishButton instance before I connect the signal to my 
own slot, otherwise the slot gets never called.

With sip-4.2.1/PyQt-3.14.1 this additional reference wasn't necessary.

Is this a bug or an intentional change? I haven't found anything 
specific in the ChangeLogs.
