I have always changed mine back to 127.0.0.1 thinking it was a bug. However, now I find:

http://ubuntuforums.org/showthread.php?t=388765 #6: Re: Performance tip for Feisty users Explanation why.

This is a fix for the new system that was started back in edgy where the host name was split off to 127.0.1.1, the problem is that some applications still look for the host name @ 127.0.0.1, so to keep those applications happy and running smoothly you simple need to add the host name where those applications expect it to be.

Also:

So I guess I'll change mine back to 127.0.1.1 to stay with the standard(?).

My current hosts file (feisty) looks like this:

127.0.0.1 localhost name.sambasharedomain 127.0.0.1 name

My old one from Edgy had:

127.0.0.1 localhost name.sambasharedomain name.sambasharedomain

I have no idea why it had name.sambasharedomain twice.
