Description:
configure mysql to build --with-csv-storage-engine.
Run the CSV test case. You should see an error.

For some reason (which I have done some research on), the optimizer is not always doing the 
right thing when it needs to do an ORDER by on a storage engine that does not support indexes.

How to repeat:
Run CSV test case.

Suggested fix:
Look at how filesort is now handling cases where no indexes are available.
