Friend Picker sample (Contacts) is broken

[Fabrice]

When I go to the "JavaScript Picker Sample For The Google Contacts
Data API" page, I see my contacts, but when I click on any of them I
get the following JavaScript alert "Error: Request via script load
timed out. Possible causes: feed URL is incorrect; feed requires
authentication".

http://gdata-javascript-client.googlecode.com/svn/trunk/samples/contacts/contacts_picker/picker.html

Is it possible to fix the sample?

When I reuse the picker in my own project, I get 401 (Authorization
required) each time I click on a contact. It seems that the request to
get a contact's details fails.

Any idea?
