crash with current git

[Richard Hughes]

With using eggdbus, PolKit1 and PolKit-gnome1 from git master, and the
polkit1 branch of PackageKit, I get the following when running the
PackageKit self checks:

(process:30125): GLib-GObject-WARNING **: invalid uninstantiatable
type `(null)' in cast to `EggDBusConnection'

(process:30125): GLib-GObject-WARNING **: instance of invalid
non-instantiatable type `(null)'

Program received signal SIGSEGV, Segmentation fault.
