model.clone() not working as exprected on translated columns

On Rails 2.3.4, given I have a record_title-model:

% script/console test

r = RecordTitle.first RecordTitle id: 10000, infotype: "SI", docno: "0258", unitno: "38", text: "Vel voluptate aliquid et doloribus sint eum ad sequ...", fun_group_id: 10000, fun_subgroup_id: 10000, created_at: "2001-11-14 23:00:00", updated_at: "2008-05-23 22:00:00", state: "draft" rc = r.clone RecordTitle id: nil, infotype: "SI", docno: "0258", unitno: "38", text: "Vel voluptate aliquid et doloribus sint eum ad sequ...", fun_group_id: 10000, fun_subgroup_id: 10000, created_at: "2001-11-14 23:00:00", updated_at: "2008-05-23 22:00:00", state: "draft" rc.text nil r.text "Vel voluptate aliquid et doloribus sint eum ad sequi."

Even after saving the newly cloned model, the text remains empty. Thus it is not cloned as all the other atributes.
