Comment (by jvcelak):

 I'm affected by this bug as well. And I can help by sending a patch. But
 I'm not sure what is the proper fix.

 I'm thinkng about the following solutions:

 1. The simplest one. Make the base implementation `UserInfoProviderBase`
 return an empty dictionary, instead of returning an username as the
 e-mail.

 2. Check if there is `@` character in the username. If it is there use the
 username as the e-mail. Otherwise, return an empty dictionary.

 3. Pass the whole user information into `getUserInfo` and make the
 implementation to decide, which parameters should be updated.

 Ideas?
