Bug Description

See https://bugzilla.gnome.org/show_bug.cgi?id=640714.

In a nutshell: The Unity places are using g_application_register() on startup. This call does a sync DBus call to own the app name on the bus. The problem is that this is broken by design because GDBus will start processing messages before you've returned to the call site of register(). This makes the caller race to register object paths before incoming methods are dispatched.

The (normal) solution would be to always register the objects before calling app.register() but we don't want to do that because our objects can be very expensive to set up.
