hosting dispatch broken

The main cronjob is dead now:

mumia:~/webroot$ php '/var/hostmaster/drupal-5.x/drush.php' hosting dispatch --root='/var/hostmaster/drupal-5.x' -v
dispatching queues
dispatching command /drush.php 'hosting' 'tasks'  '1' '5' --root='' 
sh: /drush.php: No such file or directory

That's because the publish_path is not set, for some reason:

  $drush_path = sprintf("%s/drush.php", $data['publish_path']); 

This is in:

function hosting_generate_command($system, $command, $ref, $args = array(), $options = array()) {

  $data = module_invoke_all('provision_args', $ref, $command); 
  $data = array_merge($data, $options);

I suspect this is related to this commit:
