Code review comment for lp://staging/~camptocamp/ocb-addons/7.0-fix-1311087-rgo

Development for 7.0 has moved to github on https://github.com/OCA/ocb - please move your merge proposal there if it is still valid.

(I close and reject this in order to have a cleaner overview for 6.1 MPs which indeed have to be done on launchpad)
