Problem with facebook Login - Cannot create user

Hi guys.
One of my users tried to register with the facebook button and he reported that the user was not created and he was stuck in the homepage.

I checked the error log and this is the info.

Date User Area Type Info
28/03/2014 15:44 Unknown create_new_wp_user_from_fb exception Cannot create a user with punctuation characters (#$!%&:wink: in login name.

The user e-mail and facebook profile has nothing different then any other profile, and also does not have any character.
