It's not. If you don't call osso_init() or otherwise request the
service name, D-Bus will assume your application didn't manage to
start up properly and kills the process (after some timeout, IIRC this
was about 10s at some point).

If you want other apps to be able to open files into your app, you'll
need to provide a D-Bus interface with a method to which the other app
can give the file name as a parameter. This is used for the mime-type
autolaunch for example.
