Ad Action Email Errors

I seem to be having strange errors involving the ad actions. First, I get this in my logs:

Feb 26 22:30:33 drupal: http://kpbj.com|1267252233|action|198.224.224.224|http://kpbj.com/cron.php||0||Queued email for scheduled trigger to [all_owner_emails]

Feb 26 22:30:36 drupal: http://kpbj.com|1267252236|php|198.224.224.224|http://kpbj.com/cron.php||0||file_get_contents() [function.file-get-contents]: Filename cannot be empty in /kpbj.com/htdocs/sites/all/modules/mimemail/mimemail.inc on line 244.

Then I get an email from the site with the correct ad action subject line I set up, but no email body.
