API cannot return more than 1 contact website

civicrm_contact_get is unable to return more than 1 contact website. Doing a little debugging, the correct results are returned from the query, but in CRM/Contact/BAO/Query.php, at line ~3162, only one value is written to $values. Current line is:

$values[$dao->contact_id] = $query->store( $dao );

Changing that to:

$values[$dao->contact_id][] = $query->store( $dao );

allows the data to at least not be overwritten, but causes a lot of other problems. I'm new to Civi, so I'm not really sure what the next step would be, but unless that line is changed, I don't think the API will ever be able to return more than 1 contact website (if multiple sites, i.e. twitter, facebook, main) are added to a contact.
