There is no such thing as a "GDK_DESTROY" event.

As you may notice from the "destroy" signal, the callback signature is:
void (* destroy) (GtkObject *widget, gpointer user_data);
https://developer.gnome.org/gtk2/stable/GtkObject.html#GtkObject-destroy
So you're literally looking at your user data.
You should look at the API reference for the description and signature
of a signal before connecting a callback to it.
Ciao,
Emmanuele.
