Redmine

Hello,
I've updated redmine to the 0.9RC from 0.8.5. When I try to create a new group I get an error:

ActiveRecord::StatementInvalid in GroupsController#create

Mysql::Error: Column 'hashed_password' cannot be null: INSERT INTO `users` (`created_on`, `hashed_password`, `admin`, `language`, `lastname`, `mail`, `updated_on`, `type`, `firstname`, `mail_notification`, `login`, `status`, `identity_url`, `last_login_on`, `auth_source_id`) VALUES('2010-01-30 12:46:56', NULL, 0, NULL, '23', NULL, '2010-01-30 12:46:56', 'Group', NULL, 1, NULL, 1, NULL, NULL, NULL)
