Description:
I create a trigger which has SHOW CREATE EVENT in it.
I insert, which activates the trigger. The SHOW happens.
I insert again. I get a "Packets out of order" error.

How to repeat:
mysql> create event ek on schedule every 1 year do set @a = 5;
Query OK, 1 row affected (0.00 sec)

mysql> create table tk (s1 int);
Query OK, 0 rows affected (0.01 sec)

mysql> create trigger tk_ai after insert on tk for each row show create event ek;
Query OK, 0 rows affected (0.00 sec)

mysql> insert into tk values (0);
