"youtubeSignupRequired : Unauthorized" error if the user doesn't have channel

What steps will reproduce the problem?
1. create a new google account
2. go to 
https://youtube-api-samples.googlecode.com/git/yt-upload-javascript/index.html
3. sign in with your new account
4. open your console

What is the expected output? What do you see instead?
- Creating a channel via API (v3)
- "youtubeSignupRequired : Unauthorized" error

What version of the product are you using? On what operating system?
YouTube Data API v3.0 on Mac OS X (same issue on every OS even mobile)

Please provide any additional information below.

I tried to fix it via : 
https://developers.google.com/youtube/create-channel?hl=fr , but :

- https://m.youtube.com/create_channel?chromeless=1&next=/channel_creation_done 
doesn't close itself after channel creation, and i think it's easiest to create 
channel via API.

Thanks for help
