There was a similar thread on gtk-app-devel-list@redhat.com today that I
instigated. Your problem may be different, but it sounds similar.

There's a misfeature or bug in option menus such that they only calculate
their preferred size when the menu is added. If you call
gtk_option_menu_set_menu() with an empty menu, and later add menu items, the
option menu won't automatically adjust its size to account for the length of
the longest menu item as it should. This could end up with a minimally-sized
option menu in a situation where the size isn't dependent on sibling widgets.

I don't know if this would cause no text at all to appear. If you don't call
gtk_option_menu_set_history() on a new option menu, it won't display any text
until the user selects an item. This might be why no text shows at all in your
case.
