The problem was that SHOW CREATE EVENT released all metadata locks held by the current transaction. This made any exisiting savepoints invalid, triggering the assert when ROLLBACK TO SAVEPOINT later was executed. This patch fixes the problem by making sure SHOW CREATE EVENT only releases metadata locks acquired by the statement itself. Test case added to event_trans.test.
