Browse Source 
2006-11-26  Ryan Lortie  <desrt@desrt.ca>

        * docs/reference/gtk/tmpl/gtkbuildable.sgml: add clarification stating
        that the construct_child function is responsible for returning a
        reference.
        * gtkbuilder.c (_gtk_builder_construct): remove g_object_ref() for
        objects from constructors
        * gtkuimanager.c (gtk_ui_manager_buildable_construct_child): add
        g_object_ref() to this construction function (it's the only
        implementer in GTK)

        Fixes #496645.
