Possible watchdog errors out of cron

The tentative !full_node implementation using node_view() (see #199171: CCK body) doesn't work so well. With Forum topics it calls forum_view(), which tries to call

    menu_set_location($breadcrumb);

but there's no menu during cron runs! This causes errors like the following:

array_keys() [function.array-keys]: The first argument should be an array in /srv/www/apps/drupal/drupal-5.7/includes/menu.inc on line 338.

Wrong parameter count for min() in /srv/www/apps/drupal/drupal-5.7/includes/menu.inc on line 328.

To eliminate these warnings, comment out or remove the line in subscriptions_content.module that starts with

  $mailvars['!full_node'] =
