@Pavel Troller I've checkt the /etc/hosts now. You were right, it says
127.0.0.1 localhost.localdomain localhost Zwirch
(With Zwirch the Name of this Computer)
But I can't just statically rewrite it, because I use DHCP. Also this is a fresh Ubuntu-Install, so I'm surely not the only Wine-User with such an /etc/hosts..
Hi ! Yes, I know that *MANY* well-known distros are wrong with /etc/hosts and similar files.. The trick is that specifying your hostname for localhost interface improves Linux functionality in the case that there isn't other network interface active. Otherwise, a plenty of services would not work locally. However, when a real network interface comes up, it should be changed and moved to the line with a real IP address, which is not so obvious in the real world... I think that it is NOT GOOD to patch wine to fix this case; it behaves absolutely correctly and all the problem should be solved by correctly configuring your Linux networking. Please see any good document about naming principles of network interfaces. With regards, Pavel Troller
