Hello girls, guys, I'm very surprised with this and I don't know how get rid of it.

Migrating the partner contacts from 6.1 to 7 (OCB version), I exported, modified and imported the base. Everything went find , everything looked good when I was on the webpage Sales/Customers but when I clicked on one of the contact I get the following error :

I'd like to understand what happened. How may the import created that ? I tested he same import on another install of openerp 7 (official bazaar version) but the problem didn't happen. I had a try on a fresh database on v7-OCB (same install as the one used first) but same problem happened again.

Thanks
