Hi Patrick,

Unfortunately uniqueness of email addresses is not enforced at the db
level yet.  We may look at fixing that in future, but first I think we'd
need to do a bit of work around how to upgrade old databases.  In the
meantime you should just avoid relying on uniqueness in your custom
code.

If you find any core code relying on uniqueness of emails (you mentioned
search friends, and see groups members), let us know in another bug
report, and we'll fix it for 1.5.

  When importing a LEAP2 zip  into a 1.5 Mahara site (latest   1.5.0dev

  proceeds  normally  but the mahara site then starts to fail in various
  places (search friends, see groups members) ...

  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 ;-)
