I've got a dev server we've been trying out 2.x with. We take our current 1.0.1 database, run db:migrate on it and with 2.0 it's always gone fine. Now that we went from 2.0.4 to 2.1.2 there's a problem.

When I try to create a new issue, I get a 500 error. Looking at the dev log I see this:

Mysql2::Error: Column 'position' cannot be null:
INSERT INTO `issues` (`assigned_to_id`, `author_id`, `category_id`, `created_on`, `description`, `done_ratio`, `due_date`, `estimated_hours`, `fixed_version_id`, `is_private`, `lft`, `lock_version`, `parent_id`, `position`, `priority_id`, `project_id`, `remaining_hours`, `rgt`, `root_id`, `start_date`, `status_id`, `story_points`, `subject`, `tracker_id`, `updated_on`)
VALUES (NULL, 36, NULL, '2012-11-09 14:46:59', 'asfasfasfsadf', 0, NULL, NULL, NULL, 0, 1, 0, NULL, NULL, 4, 1, NULL, 2, NULL, '2012-11-09', 1, NULL, 'test', 1, '2012-11-09 14:46:59')

I see in the database.rb that in the issues table there is a not nullable field called position. That wasn't in the 1.x database we have and there are no plugins installed so I'm pretty sure this is a stock field.

Current about:
Environment:
Redmine version 2.1.2.stable
Ruby version 1.9.3 (x86_64-linux)
Rails version 3.2.8
Environment development
Database adapter Mysql2
Redmine plugins:
no plugin installed

What are we missing that position ends up being null on the INSERT?
