Comment 8 for bug 695084

Hi, I just downloaded sources today about an hour ago. I downloaded everything fresh and I still get the exact same error when trying to install addons modules.

  File "/usr/local/lib/python2.6/dist-packages/openerp-server/tools/misc.py", line 813, in cached_result
    result2 = fn(self2, cr, *args[:self.skiparg-2], **kwargs2)
  File "/usr/local/lib/python2.6/dist-packages/openerp-server/addons/base/ir/ir_model.py", line 426, in _get_id
    raise ValueError('No references to %s.%s' % (module, xml_id))
ValueError: No references to product.group_product_manager

I cant do anything because it is impossible to install new modules or start over. Can someone tell me how to fix this? Thanks.
