It is also impossible to delete that user under site administration since getting that user data fails with the above error...

To return site to 'normal operation' one has to go to table usr and manually edit the new user email to an unique value

Cheers.

Edit : I did not tested it yet, but I do hope that this behaviour does not occur also in importing users from a CSV file ;-)
