This must be a recent change?

When I enquired (I think about 6 months ago) I was told that memory for top 
level widgets such as dialogs could be managed with manage(), and that the 
Gtk+ reference counting mechanism would deal with it (I got a firm put-down 
from Karl Nelson saying that this did not give rise to a memory leak when I 
suggested that it might).
