Hide and Hide Others are Apple functions, not Gtk ones, so the accelerators only work if 
use-quartz-accelerators is enabled. It isn't by default because it messes up the responder chain for key 
bindings by grabbing the accelerator event before it's passed to Gtk. I suppose the fix is to add 
corresponding GtkActions that call [theApp hide:] and [theApp hideOtherApplications:] to catch the 
accelerators.
