"file_save_as_cmd_cb()" does:

  /*** Packet Range frame ***/
  range_fr = gtk_frame_new("Packet Range");
  gtk_box_pack_start(GTK_BOX(main_vb), range_fr, FALSE, FALSE, 0);
  gtk_widget_show(range_fr);

  /* range table */
  range_tb = gtk_table_new(7, 3, FALSE);
  gtk_container_border_width(GTK_CONTAINER(range_tb), 5);
  gtk_box_pack_start(GTK_BOX(range_fr), range_tb, FALSE, FALSE, 0);
  gtk_container_add(GTK_CONTAINER(range_fr), range_tb);
  gtk_widget_show(range_tb);

GTK_BOX(range_fr) isn't valid - a GtkFrame is not a GtkBox (GtkFrame is 
not a subclass of GtkBox).

A GtkFrame is also a GtkBin (GtkFrame is a subclass of GtkBin), which 
is also a GtkContainer; the right call is probably a 
"gtk_container_add()" call - which we're already doing, so the 
"gtk_box_pack_start()" call should just be removed.  I've checked in a 
change to remove it.
