Errors when there are no groups or when groups have no users

I’ve been getting the following warning on user edit pages.

Warning: in_array() expects parameter 2 to be array, string given in /.../wp-content/plugins/edit-flow/modules/user-groups/user-groups.php on line 1046

I decided to wipe out the user groups to get past this for now but when i saved I got an error about having no user groups.

For now I updated user-groups.php to have a check:

if ( is_array( $all_usergroups ) && count( $all_usergroups ) ) foreach( $all_usergroups as $usergroup ) {
  if ( in_array( $usergroup->term_id, $usergroups ) )
    $this->add_user_to_usergroup( $user->ID, $usergroup->term_id );
  else
    $this->remove_user_from_usergroup( $user->ID, $usergroup->term_id );
}

I have not had a chance to see if this is because of some other plugin, etc. but it seems to me it would be best to have these kinds of checks baked in.
