I finally found a way to do it right: apparently if you try to manipulate 
_all_ of the radio buttons in a group it gets confused (for lack of a better 
word). The way to do it is to do:

if (flag_1)
 gtk_check_menu_item_set_state(GTK_CHECK_MENU_ITEM(widget1),TRUE);
else if (flag_2)           
gtk_check_menu_item_set_state(GTK_CHECK_MENU_ITEM(widget2),TRUE);
else if (flag_3)
 gtk_check_menu_item_set_state(GTK_CHECK_MENU_ITEM(widget3),TRUE);
