Answers.Body: <p>There was a bug in CiviCRM 4.6.4 that triggered the same error 'A fatal error was triggered: is not of the type Int' when trying to rebuild the smart group cache so this could be related, especially if U used smart groups for your maling.
  I would suggest upgrading to 4.6.6 on a copy installation to see if that resolves the issue. Since this is not a real answer to your question I wanted to post this as a comment but I don't have sufficient reputation points to do that. I myself upgraded to 4.6.6 after experiencing too many problems with the 4.6.4 upgrade.</p>

Comments.Text: This is a good question!  To solve your problem, we'll need to see the expanded debugging information.  In CiviCRM, please go to **Administer menu > System Settings > Debugging and Error Handling**, select "Yes" to both "Enable Debugging" and "Display Backtrace", and press "Save".  Repeat the problem that caused your error, and you'll see much a much more detailed error.  Please update this question with the expanded error and backtrace - and don't forget to disable debugging/backtrace when you're done!

Comments.Text: Hmm - I'm surprised you didn't see a backtrace - maybe it's hidden by your WP theme?  You may want to check the ConfigAndLog directory for your CiviCRM log, which should hopefully include the backtrace, and post here.
