A comma in a Household name breaks "Use Household Address" for a contact

See http://forum.civicrm.org/index.php/topic,1245.0.html for initial discussion and identification. Final (currently fourth) post indicates that "Dojo selector shows the list in the format: "display_name, street_address (upto 25 char), city" i.e three parts. Having a comma (,) in display_name is changing the format of the list causing misinterpretation of contact-ID and hence the error." The error reported is "Shared Household-ID not found".
