--- Comment #10 from Emanuel Rietveld codehotter@gmail.com 2012-06-01 13:26:22 CDT --- Thanks to a tip from lahmbi5678 this problem was solved for me. Please make sure that the output of 'hostname' (that is, your hostname) is in /etc/hosts. You can let it resolve to 127.0.0.1 or your internal ip address, either works. That is the usual configuration but sometimes this can go wrong. For example when you change your hostname without editing the hosts file.
Let's keep this bug open so other people with the same problem can find it. I believe wine should be able to help users even in spite of incorrect /etc/hosts configuration, as the hostname is still responds correctly to ping even if you don't have it in /etc/hosts
