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.
