That is no doubt the problem. When omniORB resolves "localhost", it gets
the ::1 IPv6 loopback instead of The server is presumably
only listening on IPv4 (although I'd expect it to listen on IPv6 too --
perhaps the Ubuntu package changes the default?)

omniORB 4.1.5 changed it so that if a name resolves to more than one
address, omniORB tries all of them until one works. 4.1.2 only tried the
first one.

If you don't mind being omniORBpy specific, you can access the _v
member, which is the numeric value of the enum.
