STEPS TO REPRODUCE:
1. From the reports menu, select the "Event Participants (list)" report
2. Under "Report Criteria" select the check box in the "group by" section for "Events"
3. Ensure that sorting by "last name, first name" is set.
4. Preview the report

You will be presented with the error above.

It also seems that it is possible to modify the report with the group by setting (that causes the error) and then you will be UNABLE to edit the report criteria to remove the group by setting thus rendering the report useless (it will always return an error).
