wierd runtime problem

[John Looney <John Looney hos horizon ie>]

 I'm getting odd runtime errors in any GTK program I compile now, even
something like a small hello world.

 It happens when I called GTK_OBJECT()...no idea why.

 I removed the gtk .deb pacakge, and reinstalled it. I then installed
gtk-1.0.5, and the problem was still there.

 Any ideas ?

-------------- added errors and code -------------------

 The errors are:

** WARNING **: invalid cast from `GtkWindow' to `GtkWindowType'

** WARNING **: invalid cast from `GtkWindow' to `GtkWindowType'

** WARNING **: invalid cast from `GtkButton' to `GtkWindowType'

** WARNING **: invalid cast from `GtkWindow' to `GtkWindowType'

** WARNING **: invalid cast from `GtkButton' to `GtkWindowType'

 The code is:

#include <gtk/gtk.h>
void hello (GtkWidget *widget, gpointer data)
{
    g_print ("Hello World\n");
}
    
gint delete_event(GtkWidget *widget, GdkEvent *event, gpointer data)
{
    g_print ("delete event occured\n");
    return (TRUE);
}
   
/* another callback */
void destroy (GtkWidget *widget, gpointer data)
{
    gtk_main_quit ();
}
                       
int main (int argc, char *argv[])
{
    GtkWidget *window;
    GtkWidget *button;

    gtk_init (&argc, &argv);
     
    window = gtk_window_new (GTK_WINDOW_TOPLEVEL);

    gtk_signal_connect (GTK_OBJECT (window), "delete_event",
                        GTK_SIGNAL_FUNC (delete_event), NULL);
    gtk_signal_connect (GTK_OBJECT (window), "destroy",
                        GTK_SIGNAL_FUNC (destroy), NULL);
    gtk_container_border_width (GTK_CONTAINER (window), 10);
    button = gtk_button_new_with_label ("Hello World");
    gtk_signal_connect (GTK_OBJECT (button), "clicked",
                        GTK_SIGNAL_FUNC (hello), NULL);
    gtk_signal_connect_object (GTK_OBJECT (button), "clicked",
                               GTK_SIGNAL_FUNC (gtk_widget_destroy),
                               GTK_OBJECT (window));
    gtk_container_add (GTK_CONTAINER (window), button);
    gtk_widget_show (button);
    gtk_widget_show (window);
    gtk_main ();
    
    return 0;
}
