CiviReport and smart groups returns syntax error

When CiviReport includes a smart group in the criteria, a DB Error: syntax error is thrown. It was introduced while attempting to fix CRM-7207.

Attached is the patch that corrects the syntax error (removes extra right hand parenthesis and single quotes the date). Below is the full error details dump. This happens on a clean 3.3.2 install and on demo. To reproduce, simply include a smart group in your criteria for a CiviReport.
