Already fixed in master (by 89ee1ce7906dec1b157a2db1c66fb0dc3b36b5dc, 5b3ba673c3429659e6bf6cdb9427542fa8b71afa and 2c2db2581a825b55f1079c3a3b9f0a849cb7eab3).

Thx for the info. I deleted the anonymous user before this error occured. Is there a way to bring it back via manage.py?

[nijel]

It will get created by:

./manage.py setupgroups

In admin interface it's IMHO not possible to create user with disabled login.
