or this ugly hack ;o)

i=1
while(i<the_highest_num_label):
	if(self.hasattr('label' + str(i))):
		label = self.getattr('label' + str(i))
		label.setText('')

The node traversal is probably a better solution though..  If you do the 
traversal inside __init__ on your dialog and store the resultant set of 
labels, you would only have to traverse the nodes once and you don't have to 
hard code the list of labels into every dialog.
