OK, I admittedly do not understand the above paragraph.  But my experience is 
that in order to be a CORBA server you must either start the CORBA event loop 
via one of the CORBA_* calls, or by calling one of the calls that starts the 
GTK event loop with integrated CORBA support, for instance bonobo_main().

But in my case I cannot call bonobo_main() (at least not directly) since my 
code is inside a gtk_module_init() call.  The code I am writing must return 
control to GTK.

If the GTK application that has loaded my code as a GTK_MODULE calls the 
regular gtk_main() loop, it does not service incoming CORBA requests.  But I 
cannot modify the application since this is an optional module.

At the moment I am working around this by calling "bonobo_main()" inside the 
method which is passed to the g_idle_add() call - which works, but seems 
somehow wrong.

Do you understand my goal a bit better now?

It is complicated a bit by the fact that the "register_application" call which 
precedes my call to bonobo_main() results in a callback.  At the moment I am 
coping with this by making register_application() a oneway method, but this is 
not really correct.  So perhaps I need a second g_idle_add() call inside the 
method passed to my first g_idle_add()...
