CiviCRM and views integration and DA

We have one CiviCRM installion which works with a Domain Access site. We don't use the Multisite feature of CiviCRM.
I juft tryed to aneble view intigration for CiviCRm whoch is done by adding some code to the settings.php file. Because CiviCRM has it's own Database.

$databases['default']['default']['prefix']= array(

Views intigrations works ok with CiviCRM so far, but i get this Notice as soon as i added this code into settings.php.
Notice: Undefined index: default in domain_get_primary_table() (line 266 of /srv/htdocs/sites/all/modules/domain/domain.bootstrap.inc).

So my question is, what is the right way to do this with DA?
