Joeren: Well, my suggestion was to *switch* the nameserver entries, not to replace them. I already suspected that Karmic changed the order of the DNS requests, in fact asking the last nameserver in /etc/resolv.conf first, while Jaunty asks the first nameserver.
While changing the order again wouldn't solve any problem here, but people with a single broken DNS server wouldn't notice the change as a regression, since it worked for them in Jaunty and it might still work for them with Windows.
