I think the keys-changed signal is bounded to GtkWindows, isn't it ?
http://developer.gnome.org/doc/API/2.0/gtk/GtkWindow.html#GtkWindow-keys-changed

The "keys-changed" signal
void        user_function                  (GtkWindow *window,
                                            gpointer user_data);

The signal is "keys-changed".

It seems you're tracking the signal on the keymap, that's not a GObject
so cannot deal with signals at all.

Try to track the signal on your applications main window.

g_signal_connect (G_OBJECT (theWindow), "keys_changed",
                             CALLBACK (someFunction), (gpointer) someData);

void someFunction  (GtkWindow *window, gpointer user_data)
{
        GdkKeymap* keymap;
        keymap = gdk_keymap_get_default();
        ...
}

I did not tried this as I never dealed with keyboard changes, but may be
it could work.
