First of all, this message should probably have been sent to gtk-list
rather than gtk-devel-list.  This list is for development of gtk, rather
than with gtk.

The option menu reparents the contents of the selected menu item into the
button so that it gets displayed when the menu is not popped up.  So the
active menu item having no child is not unexpected.

You can get the selected GtkMenuItem as
GTK_OPTION_MENU(option_menu)->menu_item, and the label that would usually
be inside the menu item as GTK_BIN(option_menu)->child.
