civicrm_handler_field_email::render_link() not defined, breaks views that have CiviCRM Email fields

When trying to display a CiviCRM: Email field in a Drupal view (see attached view export) using Drupal 6.13 with Views 6.x-2.6 , PHP dies with the following error:

Fatal error: Call to undefined method civicrm_handler_field_email::render_link() in /usr/local/apache/vhosts/staging.crl.edu/sites/all/modules/civicrm/drupal/modules/views/civicrm/civicrm_handler_field_email.inc on line 38

Clearly, civicrm_handler_field_email::render_link() is not defined, nor is it defined in views_handler_field, the parent class of civicrm_handler_field_email.
