well, that behaviour is what i would expect. After all, the machine knows that 
to ping its own ip, it has to use the lo0 interface.
It just resolves your ip with the hostname of the machine.
So as far as i see, this is the intended behaviour.

(You can use netstat -rn to see the actual ip and not hostnames.)

If you can't ping localhost, i'd say that the problem lies elsewere. 
(firewalls probably)
You can check with tcpdump to see what happens and your pings don't get a 
reply.
