Nope, I'm unable to reproduce the problem by adding "iface eth0 inet6 auto" and "iface eth0 inet dhcp" and running restart networking. I have not enabled proposed updates. Are there any other steps in the reproduction? I'm not sure that this machine has used the alternate installation, and it has been upgraded at least once.
