How to fix socket.gaierror: (11004, 'getaddrinfo failed') error in GAE?

I'm using Aptana and GAE. When I run GAE launcher or run a server in Aptana 3, I get this error... I've downloaded the lastest version of GAE and still doesnt work...

Traceback (most recent call last):

FIXED! after days looking for this problem: I just deleted this line "0.0.0.0 localhost " from my hosts file located in "C:\Windows\System32\drivers\etc" thanks anyway!!

Had same problem here, I had to add

127.0.0.1 myhostname

and

::1 myhostname

to /etc/hosts
