D7: When someone registers an account in English (default language) the registrant is redirected to the Login page with a message: "A welcome message with further instructions has been sent to your e-mail address."

So far, so good.

But when a registrant select a foreign language on the registration page (like es for Spanish,) he is redirected to his home page after submitting his registration.

Anyone knows how to fix this bug so that it behaves like the English registration? Or a workaround?

Any help on this is much appreciated. :)
