You can do it explicitely by using g_object_add_weak_pointer (your_object, (gpointer) &your_object) which sets your_object to NULL when it is destroyed. See http://library.gnome.org/devel/gobject/unstable/gobject-The-Base-Object-Type.html#g-object-add-weak-pointer for more information. Note that this will only work for the variable your_object. For other pointers to the object you'd have to do the same. - Jannis
