There is an error in the sql where a semi-colan has been accidently placed into the questiontype.php file on like 919. I have removed this error and uploaded a patch for the fix
Go into a quiz and try to create a new question eg http://moodle-techdev.cqu.edu.au/question/question.php is the page that will cause the error.
