[omniORB] Object::_get_interface() always returns nil ref.

Hi,

I'm working on `omniifr' an implementation of the Interface Repository.
The first draft is very nearly complete, but I'm having trouble with
omniORB's implementation of the Object::_get_interface() method - it
always returns a nil reference!

See the attached test program and logfile. The test program simply
resolves an init ref to the InterfaceRepository, and then calls
_get_interface() on the Repository itself. (This should successfully
return an InterfaceDef_ptr, because I've previously loaded ir.idl into
the repository.)

The trace shows the following sequence:

1. test program requests ifr's _interface method.
2. ifr's ORB successfully resolves initial ref to the
   repository (which happens to be itself).
3. Call to Repository::lookup_id() is requested and returns
   sucessfully with the InterfaceDef reference.
4. Nil reference is returned to test program.

So, the problem seems to occur between steps 3 and 4.

Anybody have a clue?
