Just some more info about the matter. The signal "drag-data-received" 
is connected to the mainwindow this way:

MainWindow = gtk_window_new (GTK_WINDOW_TOPLEVEL);

gtk_drag_dest_set (MainWindow,GTK_DEST_DEFAULT_ALL, drop_targets, 1, 
GDK_ACTION_COPY | GDK_ACTION_MOVE | GDK_ACTION_LINK | GDK_ACTION_ASK);

g_signal_connect (G_OBJECT (MainWindow), "drag-data-received", 
G_CALLBACK (on_drag_data_received), NULL);

Then a notebook widget is added this way:
/* Create the notebook widget */
notebook = GTK_NOTEBOOK(gtk_notebook_new() );
gtk_box_pack_start (GTK_BOX(vbox_body), GTK_WIDGET(notebook),TRUE,TRUE,0);
gtk_notebook_set_tab_pos (notebook, GTK_POS_TOP);
gtk_notebook_set_scrollable (notebook, TRUE);
gtk_notebook_popup_enable (notebook);
gtk_widget_show (GTK_WIDGET(notebook));

g_signal_connect ((gpointer) notebook, "switch-page", G_CALLBACK 
(xa_page_has_changed), NULL);

When a new page is added to the notebook I connect these signals for 
drag and drop:

g_signal_connect (G_OBJECT (archive->treeview), "drag-begin", 
G_CALLBACK (drag_begin), NULL);

g_signal_connect (G_OBJECT (archive->treeview), 
"drag-data-get",G_CALLBACK (drag_data_get), NULL );

g_signal_connect (G_OBJECT (archive->treeview), "drag-end",	 
G_CALLBACK (drag_end), NULL);

Under gtk 2.8.20 the signal drag-data-received is emitted when the 
notebook is empty (no pages) and when some pages are added to it.

Under gtk 2.10.6 the signal is not emitted at all in both cases.
What can I do to have to drop detected when the notebook has no pages 
(my window app empty) and when it has some ones?

P.S. I even tried to connect the drag-data-received to the 
archive->treeview as showed above but nothing to do; the signal
is not emitted anyway.
