Ok. Here it is:

#!/usr/bin/env python
#
# focusouttest.py
#

import sys
from qt import *
from qtpe import QPEApplication

class Dlg(QDialog):
     def __init__(self):
	QDialog.__init__(self, None, None, True, 1)
	self.setCaption("FocusOut Test")
	self.playerList=["", "Pete", "Volker"]
	self.wCmbList=[]

         self.layout=QVBoxLayout(self)
	self.placeEdit=QLineEdit(self)
	self.layout.addWidget(self.placeEdit)
	
	for i in range(4):
	    cmb=Combo(True, self)
	    #cmb=QComboBox(True, self)
	    #cmb.installEventFilter(self)
	    for p in self.playerList:
		cmb.insertItem(p, -1)
	    self.wCmbList.append(cmb)
	    self.layout.addWidget(cmb)
	
     def eventFilter(self, o, e):
	if e and o:
	    if e.type()==QEvent.FocusOut:
		for cmb in self.wCmbList:
		    if o==cmb:
		    #if o==cmb.lineEdit():
			QMessageBox.information(self, "Info", "Bingo")
	return False

class Combo(QComboBox):
     def __init__(self, *args):
	QComboBox.__init__(self, *args)
	self.installEventFilter(self)
	self.setFocusPolicy(QWidget.StrongFocus)

     def eventFilter(self, o, e):
	if e and o:
	    if e.type()==QEvent.FocusOut:
		#if o==self:
		if o==self.lineEdit():
		    QMessageBox.information(self, "Info", "Bingo")
	return False

if __name__=="__main__":
     app=QPEApplication(sys.argv)
     QObject.connect(app, SIGNAL('lastWindowClosed()'), app, SLOT('quit()'))
     win = Dlg()
     app.setMainWidget(win)
     win.show()
     app.exec_loop()

I tried installing the event filter in the dialog itself without a 
special Combo class: no effect at all.

And with the special class there is no difference whether installing the 
filter in the dialog or in the Combo class. It get double message boxes 
and segmentation fault.
