There seems to be a related problem in omniInternal.cc (omni::createObjRef,
line 558):

  proxyObjectFactory* pof = proxyObjectFactory::lookup(mostDerivedRepoId);

  if( pof && !pof->is_a(targetRepoId) &&
      strcmp(targetRepoId, CORBA::Object::_PD_repoId) ) {
    if( omniORB::trace(10) )
      omniORB::logf("Cannot create reference -- %s is\n"
                    " not a base for %s.", targetRepoId, mostDerivedRepoId);


This returns a nil reference if the information supplied in
mostDerivedRepoId isn't really the most derived interface (e.g. if
mostDerivedRepoId says omg.org/CORBA/Object but it really is a more derived
interface)


bye, Christof
