Unfortunately you didn't understand correctly. What Scott meant was
that the slot connected to the singleshot should download the stuff with
urllib, then update the listwidget and then return control to the event
loop (and if jours is not empty schedule another singleshot timer).

Something like this should work:

class radioProgDialog(QDialog, radioUi):
    def __init__(self):
        QDialog.__init__(self)
        # Set up the user interface 
        self.setupUi(self)
        self.connect(self.btnGo,SIGNAL("clicked()"),self.extraire)
        #

    def updateGui(self):
        d=self.d
        jour = self.jours.last()
        self.jours.removeAll( jour )
        next_url=url % jour
        p=urllib.urlopen(next_url).read()
        self.d=DateFromTicks(jour)
        logText=u'téléchargement %02d/%02d/%d' % (d.day,d.month,d.year)
        self.log.insertItem(0, QListWidgetItem(logText))
        self.progressBar.setValue(self.progressBar.value() + 1) 
        print logText
        if( self.jours.isEmpty() ):
           QTimer.singleShot(0, self.updateGui)
            
        
        
    def extraire(self):
        self.url='http://www.radiofrance.fr/francevivace/prog/index.php?time=%u'
        # 
        self.jours=[(int((now() + (j * oneDay)).ticks())) for j in range(0, 4)]
        self.progressBar.setMaximum(len(jours))
        self.progressBar.setValue(0)
        print 'maxi', self.progressBar.maximum()
        QTimer.singleShot(0, self.updateGui)
        print 'fini Vivace'
