Getting core when swapping menus on an optionmenu.

Hi,

This is my first stab at creating a gnome app and everything has been going very well so far.  I am having one problem that I can't figure out, however.  What I'm trying to do is swap menu's on a GtkOptionMenu during runtime.  I wrote the following function to do so.  It works the first time it is called, but the second time it fails at the gtk_option_menu_remove_menu.

void populate_get_ofindir_dlg_optionmenu ( gchar *gsz_directory ) {
        int i;
        gchar *gsz_subdirectory;

        GtkWidget *new_menu;
        GtkWidget *menu_item;

        /* Remove the old menu. */
        gtk_option_menu_remove_menu ( GTK_OPTION_MENU ( get_ofindir_dlg_optionmenu ) );

        /* Populate with new contents. */
        new_menu = gtk_menu_new ();
        gsz_subdirectory = gsz_directory;

        i = 0;

        do {
                menu_item = gtk_menu_item_new_with_label ( gsz_directory );
                gtk_widget_show ( menu_item );
                gtk_menu_append ( GTK_MENU ( new_menu ), menu_item );
                if ( i ) { g_free ( gsz_subdirectory ); }
                gsz_subdirectory = gsz_directory;
                i++;
                if ( strcmp ( gsz_directory, "/" ) == 0 ) { break; }
        }
        while ( ( gsz_directory = g_dirname ( gsz_subdirectory ) ) );

        /* Attach the new menu. */
        gtk_widget_show ( new_menu );
        gtk_option_menu_set_menu ( GTK_OPTION_MENU ( get_ofindir_dlg_optionmenu ), new_menu );
}

Does anyone have some insight into what I'm doing wrong?

Thanks,
Chad
