Could it be (I don't use Kerberos) this tricks Kerberos into associating
127.0.0.1 with your FQDN, so it works for the first person to request
it, and then breaks for everyone else?

Also, bear in mind I think in certain setups /etc/hosts is redundant.
Don't you specify somewhere a list of services to use to look up
computer names, and if /etc/hosts is missing/disabled in that list, it
gets ignored?
