The leading zeroes in the wchars will make g_print and the NSString import routines think that you've submitted a zero-length string, because they expect single-byte characters. You can test it by transcoding the result of gtk_menu_item_get_label in your g_print statement.

Interesting, that's different from your earlier list, where you had pointers on every line, but no text in either my_label or the passed-in menuitem. It sure looks like the GtkMenuItems aren't fully initialized yet.

I think best results are obtained if you delay calling ige_mac_menu_set_menu_bar at the last possible point before returning control to the user, and then calling ige_mac_menu_sync at the end of functions that change the menu structure, again just before returning control to the user.
