capplets segv (orb->root_poa == NULL)

[Martin Baulig <martin home-of-linux org>]

I get this error both with latest ORBit and with the FOR_PANEL version,
latest gnome-libs and gnome-core.

Seems this is some CORBA problem where it fails to set up the root_poa:

        CORBA_exception_init(&ev);

        gnomelib_register_popt_table(cap_options, "capplet options");

        orb = gnome_CORBA_init_with_popt_table (app_id, app_version,
                                                argc, argv, options,
						flags, return_ctx,
						GNORBA_INIT_SERVER_FUNC, &ev);

        /* setup CORBA fully */
        POA_GNOME_capplet__init(&poa_capplet_servant, &ev);
        poa = orb->root_poa;

        /* setup CORBA fully */
        POA_GNOME_capplet__init(&poa_capplet_servant, &ev);
        poa = orb->root_poa;
	^^^^^^^^^^^^^^^^^^^

This is NULL.

	PortableServer_POAManager_activate
		(PortableServer_POA__get_the_POAManager(poa,&ev), &ev);

        PortableServer_POA_activate_object_with_id(poa, 
                                                   &objid,
						&poa_capplet_servant, &ev);
        capplet = PortableServer_POA_servant_to_reference
			((PortableServer_POA)orb->root_poa, 
			&poa_capplet_servant, &ev);

And here segfaults.

Any ideas how to fix this ?
