Looks like something somewhere is a bit broke in these lines of code then:

static void remove_list_from_panel(GtkWidget *widget, GtkWidget *main_vbox)
{
  gtk_container_remove(GTK_CONTAINER(main_vbox), remove_list);
}

static void remove_panel()
{
  gtk_signal_connect(GTK_OBJECT(remove_panel_window), "destroy",
GTK_SIGNAL_FUNC(remove_list_from_panel), &main_vbox);
}

Does this help?
