Eclipse help won't show under Ubuntu

Question

Whenever I open some help within eclipse I get a page saying:

Server Error. The following error occurred: [code=CANT_CONNECT_LOOPBACK] Cannot connect

Make sure your /etc/hosts file is properly done. Usually

• if the line containing 127.0.0.1 has your host name remove it and just leave 'localhost'
• if the opposite were true, try adding your hostname to it :)

such things happen because gnome is trying to match hostname and sockets to handle UI things. Might be worth asking on superuser..
