Not directly a solution to your problem, but...

You can make a directory browser by using a standard file selection dialog
with the file_list hidden:

  GtkWidget *dirbrowser;

  dirbrowser = gtk_file_selection_new("Directory browser");

  /* hide the files */
  gtk_widget_hide(GTK_FILE_SELECTION(dirbrowser)->file_list);

  /* connect signals */
  /* show widget */
  gtk_widget_show(dirbrowser);
