What you're seeing here is the corba server calling into a component
that has been deleted. Normally, the server should be disposed when
the component is deleted, such that the proxy gets a corba exception.
This is today done by automatically installing a helper service in
each 'corbanized' component that informs the corba machinery when it
is being freed.

For some reason this mechanism is failing.
