Comment 8 for bug 69941

Also I had the same problem. But in my case I had something in /ets/hosts:
127.0.0.1 localhost

And also an undesired
127.0.1.1 mylaptopname.mycompany

(where of course mylaptopname and mycompany are my laptop name and my company... :-) )
The second may ahave come from the fact I gave my company's domain as default domain.
I cured the problem by removing the second line and changing the first line to
127.0.0.1 localhost mylaptopname

Thankyou very much for the support
