[Ryan Lortie <ryanl src gnome org>]

commit 811bc4c24f2c5ef91813f8bd2de94859aee0c6ba

    Make use of new GHashTable API
    
    Use the new GHashTable APIs just added to GLib.  This requires the
    latest git versions of GLib and Vala to build.
    
    Also, don't add '/selinux' to the excluded list twice.
