the container (scrolled window) takes ownership of the
object you add to it and sinks it. All GTK+ containers
behave like this. You need to change your code to:

  gtk_object_ref (object1);
  container_add (container, object1);
  ...
  container_remove (container, object1);
  container_add (container, object2);

Then don't forget to unref your object as soon as you
don't need it anymore.


Salut, Sven
