[Bug 72346] System unusable when internet connection down and domain name set

[Kamil Páral]

Public bug reported:

Ubuntu Edgy.

If you set your domain name in
System->Administration->Networking->General->Domain name
and reboot your pc with network cable unpluged, you discover a serious problem.

Computer boots ok, but logging into Gnome session take about one minute,
maybe longer (ussualy it is 15sec). After that, starting every single
program (Nautilus, Terminal, Gedit, etc) take about 30sec. When you
switch from X to console, you'll find out, that some commands are
working ok, and some not (midnight commander is also waiting about 30sec
before showing up). Wow.

I tried this on two my computers (both Edgy), at both experiencing the
same problem. The computer is literally unusable.

When I unset my domain name (set it to empty line), everything starts to work fine, even if the internet connection is still unpluged.
(When unsetting domain name,beware this bug

You also have to change localhost aliases manually.)

At both computers, I have network set this way (of course different IPs):
configuration: static IP address
IP address: 192.168.0.2
subnet mask: 255.255.255.0
gateway address: 192.168.0.1
dns servers: 192.168.0.1

Expected behaviour: computer should work as usual even when domain name
is set and network cable is unplugged.

This is really serious and annoying problem, I guess.
