The problem is that  the gtk_widget_destroy is destroying the dialog,
but the static variable is never beening set back to NULL, so it tries
to raise the old destroyed dialog, and so crashes.

What you need to do is
static GtkWidget * dialog=NULL;
if (!dialog)
{
      dialog = gcp_dialog_new_show ();

      /* This will set dialog back to NULL when it is destroyed 
          NB: gtk_widget_destroyed, and not gtk_widget_destroy */
      gtk_signal_connect (GTK_OBJECT (dialog), "destroyed",
                                        GTK_SIGNAL_FUNC
(gtk_widget_destroyed), &dialog);
} else {
     /* Etc */
}
