[Ryan Lortie <ryanl src gnome org>]

commit 3b1b04433cdc1f1685af2e9c5437e3ac41f3a94a
Author: Ryan Lortie <desrt desrt ca>
Date:   Sat Jun 8 17:31:09 2013 -0400

    Add a testcase for DBusActivatable=true
    
    Add a fairly realistic testcase that ensures that GDesktopAppInfo with
    DBusActivatable=true can successfully talk to GApplication for a variety
    of purposes.
