GlademmData contains the accelerator pointer. Since every toplevel 
window has exactly one Glib::RefPtr<Gtk::AccelGroup> you have to pass it 
to subwidgets (if they ever might plan to use accelerators).

Normally every widget derived from Gtk::Window does not have a 
GlademmData * argument to the ctor.

So I think that glademm does not yet know that FileChooserDialog is a 
descendant of Dialog (and Window) and treats it like a label [defaul]. 
Simply take src/writers/fileselection.cc as a template to create 
filechoserdialog.cc (should be about 2-20 min work). Once it works send 
it to me and I'll put it into the mainline sources. [IIRC 
filechooserdialog is brand new 2.4 stuff]

If you run into trouble feel free to contact me again
