It doesn't matter with getOpenFileName. The problem is with getSaveFileName

http://doc.trolltech.com/4.1/qfiledialog.html#getSaveFileName
 "return a file name selected by the user. The file does not have to exist." 

 if not self.fileName.isEmpty():
	#save 
	pass
else:
        QtGui.QMessageBox.information(self,self.tr("Information") ,self.tr("Please specify the filename to save to"))

Message box is always displayed if the filename is empty.
