gdbus - register handler/object on interface NULL

[Bernhard Schuster <schuster bernhard googlemail com>]

I have to deal with a closed source server being based on qt + dbus.

I try to connect to it via gdbus,glib.

The connection works as follows:

A mehod/object called "message_handler" has to be registered to the bus /exported.

I call a remote method named "send_data", afterwards the service/server calls the local "message_handler". Unfortunately it expects the method/object to be at interface NULL, at least that is what I read from the dbus-monitor/bustle logs

g_dbus_connection_register_object does not allow a interface NULL pointer.

Any help or pointers are appreciated.

I opened a pretty detailed question on stackoverflow

Thanks in advance!
