Open atrium errors

Hello,

I ran into your module while looking for a solution to allow non-users of an organic group to view posts made inside a private group. All of this in open atrium though.

I get these errors when trying to review a node inside a group:

    * warning: array_fill() [function.array-fill]: Number of elements must be positive in /var/aegir/platforms/oab4/drupal-6.15/includes/database.inc on line 253.
    * warning: implode() [function.implode]: Bad arguments. in /var/aegir/platforms/oab4/drupal-6.15/includes/database.inc on line 253.
    * warning: array_keys() [function.array-keys]: The first argument should be an array in /var/aegir/platforms/oab4/drupal-6.15/modules/user/user.module on line 502.
    * user warning: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ')' at line 1 query: SELECT p.perm FROM role r INNER JOIN permission p ON p.rid = r.rid WHERE r.rid IN () in /var/aegir/platforms/oab4/drupal-6.15/modules/user/user.module on line 502.

I get "access denied" and those errors for anyone trying to view nodes in a group. Even user1 cant access nodes in a group.

I was trying to test this with node access user reference. Even without that module installed I get these errors.
