 Well, if you delete it now then it will be double-delete when I fix
 the bug. I'm interested, in what kind of application is the occasional
 leak based on GUI interaction such a critical problem?
 
 re. dispose: Maybe. I will investigate. It has worked so far elsewhere.

+We have a application where we pop up many Gtk::Dialogs for data 
+input.
+
+The application is supposed to run several hours, maybe days or weeks 
+or even month (I actually dont believe that, but my boss does)
+
+And in the gtkmm 2.0 there was only a little memory leak whereas my 
+collegue (she found the leak originally) said that with gtkmm2.2 the 
+memory leak was even bigger.
+
+I have to ask her how much memory it actually was.
