Can not add my computer to my account

[Goyo]

Binary package hint: ubuntuone-client

After opening Ubuntu One client my browser (usually Epiphany but I also tested abrowser) shows a web page asking me to authenticate. It seems to know who I am so I press Sign In and then I'm asked to add my computer to my Ubuntu One account. I press Add This Computer ant then I get this error:

-----------------------------------------------------
Unable to load page

Problem occurred while loading the URL http://localhost:58996/?nonce=2984585&oauth_token=RH2Xh0fJPzRRwBthSrLk&oauth_verifier=4e353fec-08ac-4f48-928b-da86da7e699b&return=https://one.ubuntu.com

Cannot connect to destination
----------------------------------------------------

Seems like I'm expected to be running some kind of server but I'm not?
