This is how I do it:
Carlos

GtkWidget *option_menu, *menu, *menu_item, *menu_item_active;

option_menu = (GtkWidget *) gtk_object_get_data (GTK_OBJECT (dialog), "option_menu_something");
menu = gtk_option_menu_get_menu (GTK_OPTION_MENU (option_menu));
menu_item_active = gtk_menu_get_active (GTK_MENU (menu));

menu_item = (GtkWidget *) gtk_object_get_data (GTK_OBJECT (dialog), "menu_item_a");
if (menu_item == menu_item_active) do_this ();
menu_item = (GtkWidget *) gtk_object_get_data (GTK_OBJECT (dialog), "menu_item_b");
if (menu_item == menu_item_active) do_that ();
etc...
