Editing Option Group "Contact edit options" breaks the Contact editing form (phone, email, etc. part)

When an option e.g. "email" of option group 'contact edit options' is updated (I changed the label from 'Email' to 'Adresse électronique'), the filter column in table "civicrm_option_value" is set to "0" instead of "1". This causes then the following fatal error when editing a contact:

PHP Fatal error: Call to undefined method CRM_Contact_Fo
rm_Edit_Email::setDefaultValues() in /var/www/drupal-7.12-beta/sites/all/modules
/civicrm/CRM/Contact/Form/Contact.php(361) : eval()'d code on line 1

See in the attachment the related extract from table 'civicrm_option_value' BEFORE and AFTER update to option 'Email' of option group 'contact_edit_option'.
