havoc is right in that people should usually do ref/sink on gtk objects.

however, conceptually GtkObject is just a normally ref counted object
and the floating flag is a kludge for widgets to maintain the gtk specific
API semantics of gtk_container_add() automatically taking over initial
ownership.

but if you use GtkObject in a normally refcounted framework other than the
gtk widget framework, you should be able to simply do
  o = gtk_object_new (GTK_TYPE_OBJECT, NULL);
  gtk_object_unref (o);
and ignore the gtk specific floating kludge.

of course, this is becoming less important with 2.0, since now people
can actually derive from GObject if they just need an object system
base type and don't want to fool with widgets.
