This happened to me after upgrading to Hardy Beta. I changed the domain using the Network Manager GUI and the entry "127.0.0.1 HOSTNAME.DOMAIN_NAME was added to /etc/hosts. When I deleted the .DOMAIN_NAME portion of the entry using the Network Manager GUI, the problem was resolved. Hope this helps.
