The rest of the story will be found in /etc/hosts.  I never assume
someone else's system is correctly set up.  But that :0.0 entry has to
map to something (hostname or ip).  When is localhost != 127.0.0.1? 
When /etc/hosts has been set up incorrectly like this perhaps:
127.0.0.1  myhostname
because perhaps during installation the network wasn't set up, so the
helpful distro install did something bozo.  I've seen it often enough.
