[trunk] Incorrect message when you define incorrectly a view

When you create a view and set a model incorrectly (I mean name doesn't exist) the traceback you receive is:

2012-11-12 04:27:27,241 20775 ERROR cms openerp.addons.base.ir.ir_ui_view: Can't render view for model: cms
Traceback (most recent call last):

    fvg = self.pool.get(view.model).fields_view_get(cr, uid, view_id=view.id, view_type=view.type, context=context)

<record id="view_cms_search" model="ir.ui.view">

IMHO we should receive "View X is bad defined we can't find model YYY"

I will make an MP.

Thanks.
