CCK Datetime field "Link this field to its node" gives bad url

path it produces is wrong:

http://www.mysite.com/node/nid

it has the literal string 'nid' instead of the actual nid value.

here is the exported view:

$view = new view;
$view->name = 'class_sessions';
$view->description = 'Class sessions';
$view->tag = '';
$view->view_php = '';
$view->base_table = 'node';
$view->is_cacheable = FALSE;
$view->api_version = 2;
$view->disabled = FALSE; /* Edit this to true to make a default view disabled initially */
$handler = $view->new_display('default', 'Defaults', 'default');
