Comment 1 for bug 1108215

I think that's because of the change you've made at http://bazaar.launchpad.net/~openerp-community/openerp-mgmtsystem/nc-extend/revision/58.1.1

OpenERP doesn't seem to be able to handle the column name change automatically. In the database, the column name stay to their old (and wrong) names. We'll have to add a migration script to rename the columns manually.
