Content type subscriptions not sent with cron enabled

I aplogise if this has already been submitted, but I am using V1.67 with Drupal 5 and I found that content type subscriptions didn't send when cron was enabled. I added this line in the subscriptions_heldnodes function to resolve this issue.

$strsent = $strsent . subscriptions_mailvars($onode->type, $onode->nid, $poster, 'type', $strsent);

The function already handles the other types of subscriptions, just not content type.
