Comment 5 for bug 391173

What you mean if I do need this configuration? Of course I need... Heres the file:

$ cat /etc/network/interfaces
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet dhcp
dns-nameservers 127.0.0.1
dns-search optinet.cz

It wont crash every time. Sometimes (after boot), restart helps.
