Description:
The master does not check whether the Log_event_type of a binlog event is valid before sending it to the slave.

How to repeat:
Corrupt the bytes in the binlog that store the event type.

Suggested fix:
Add a function is_valid_event() that determine whether the event type for a replication event is valid. Call that function before sending the data to a slave.

Thank you for a reasonable feature request.
