Maybe, but it is an easy one to workaround.  The splitter does some 
internal housekeeping in its EVT_SIZE handler.  Since there isn't a size 
event between the time that you do the split and when it gets maximized, 
then that housekeeping isn't done until after the maximize takes place, 
after it has already resized the lower pane.  So if you add this after 
doing your split then it will work as you expect:

         self.splitt.SendSizeEvent()
