OK, I see, I was looking at odoo/odoo test, and this is the message:
```
2014-08-06 14:56:07,690 23135 ERROR openerp_test openerp.tools.yaml_import: (u'No period found', '')
```
But in OCB this is fixed. I remember that this was a base problem. Maybe for odoo/odoo test we must exclude the conflictive module.

I'm fixing both things. Thanks for pointing out.
