And that's exactly where it fails since it traverses the widget
hierarchy which the menu is not a part of. It's own hierarchy looks
something like:
GtkWindow
\- GtkMenu
\- (multiple GtkMenuItems)
Looking at the code, the GtkWindow is the menu's toplevel window (the
menu itself derives from GtkMenuShell which is in turn a GtkContainer
so it can not be onscreen otherwise) and thus it is in it's own
hierarchy.
This coupled with the fact that the glade function has no reference to
menu hierarchy (as it is created by the AppView) makes it impossible
to find with the standard lookup method.

This sounds a bit strange, since the HildonApp is a GtkWindow (though
the type and name should state HildonApp of course) which has multiple
HildonAppViews (derives from GtkBin) as it's children (although it
only shows one at a time).

I understand. So the GtkWindow, which is the top level widget of an HildonAppView's own menu, is not in any way referrable to the HildonApp to which that HildonAppView is attached?
If this is the case, I don't see any other way to solve the problem apart from maintaining a global reference for the HildonApp and modifying the glade lookup function to get the right pointer to the HildonAppView through that reference directly, without traversing one object's hierarchy anymore.
