Allow user to use "Social login" AND "default login" to access one account

My account was created using "default login" (normal form). Today i tried to login using "social login" and "speakerfight" says: "Você já tem uma conta, mas escolheu o provedor errado para acessar desta vez. Clique aqui para ser redirecionado para a página correta."

As user, is not good to know that i'm wrong when i'm trying to do something that i think to be right.

In my opinion, if Speakerfight know that i have one account and i'm the owner, the behavior must be: just login and associate all "social login" to "default login" and i'll have "N" ways (Form, Facebook, Google, Twitter, etc) to login using the same account.

Thank's.

(sorry about my poor english)
