Cannot add any account using Online Accounts on 14.04

Status changed to 'Confirmed' because the bug affects multiple users.

Error when I launch the dialog and click "Google" , what can I do to fix this?

$ online-accounts-preferences

This is what I get when I try to add a Google Account (see attached screenshot).

Well actually this is happening with Facebook, Google, Twitter, Flickr, Evernote accounts, not with the others (Ubuntu One gives me a white screen instead of a black one). I have Utopic with all updates installed.

Same problem like Carla Sella here.

I have the same problem with Carla Sella, any updates with this bug?

Same bugs like Carla Sella.
I noted this: istalling and logging in gnome-shell the problem disappear because the system don't use online-accounts-preferences.

Any idea about this bug? I have 14.04.2 installed and it just keeps going back to the main Online Accounts page.
It is currently affecting all available options for myself.

Is there a way I can collect more information? Perhaps it is the way it is accessing the services?

@Rey Leonard Amorato if you are using Virtual Box and if 3d acceleration is enabled, try to turn off that feature and try to log in. This way helped me when I was getting blank page instead of login screen in online accounts.
