PDOException: SQLSTATE[42S22] Column not found: 1054 Unknown column 'session_id' in 'field list

I would like to report this from our testing enviroment to put on record for whom it may concern.

Error message: PDOException: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'session_id' in 'field list': INSERT INTO {mollom} (entity, id, session_id, form_id, changed, moderate, spam) VALUES (:db_insert_placeholder_0, :db_insert_placeholder_1, :db_insert_placeholder_2, :db_insert_placeholder_3, :db_insert_placeholder_4, :db_insert_placeholder_5, :db_insert_placeholder_6); Array ( [:db_insert_placeholder_0] => comment [:db_insert_placeholder_1] => 20 [:db_insert_placeholder_2] => 11091628f9d2cf9dd0 [:db_insert_placeholder_3] => comment_node_article_form [:db_insert_placeholder_4] => 1316190131 [:db_insert_placeholder_5] => 0 [:db_insert_placeholder_6] => 1 ) in drupal_write_record() (line 6868 of /www/----/x-x-x-x-x/y-y-y-y-y/includes/common.inc).

Info: Drupal 7.8 with latest mollom release and commenting anonymously providing email,homepage message input.

You can reproduce it here: http://www.digidog.de (please rush by checking link, I'll keep it up only some hours left to avoid repeating errors showing our server path) (EDIT: uninstalled mollom now to prevent further error messages.)

reproducable only on last completion step if there is no form check failed.
