    Description

      This was discovered while testing MDL-31319, and was previously reported in the forums: http://moodle.org/mod/forum/discuss.php?d=188821. This error occurred when I attempted to restore a quiz which I had deleted from the course. Note that this was the second time I had done so with this course, so the process was like this:

      1. Create quiz.
      3. First student attempt.
      2. Backup quiz.
      3. Delete quiz.
      4. Restore quiz (success).
      5. Second student attempt.
      6. Backup quiz.
      7. Delete quiz.
      8. Restore quiz (fails).

      Here's the stack trace:
