gdbusobjectmanagerserver: allow exporting itself

It is not possible to implement an object manager that exports itself and adds it's own path to the managed objects due to an assert in g_dbus_object_manager_server_export_unlocked().
Comment 1 Jonas Holmberg 2015-11-20 13:04:08 UTC 
Long version: I ran into this problem when trying to implement a bluez gatt service using gdbus in gio (not to be confused with gdbus in bluez). According to https://kernel.googlesource.com/pub/scm/bluetooth/bluez/+/5.36/doc/gatt-api.txt#274 the path of the object that implements org.bluez.GattService1 and org.freedesktop.DBus.ObjectManager must be one of the objects the are returned when calling org.freedesktop.DBus.ObjectManager.GetManagedObjects otherwise the service will not be accepted by org.bluez.GattManager1.RegisterService (https://kernel.googlesource.com/pub/scm/bluetooth/bluez/+/5.36/doc/gatt-api.txt#312).
Comment 2 Jonas Holmberg 2016-01-11 16:06:58 UTC 
It turned out to be a design error in the BlueZ D-Bus API, which has been fixed now:
