Bug #40001 Replication failure on RBR + no PK + field with index + field with no index

Description:
When issuing UPDATEs on a table with no primary key but with both indexed and non-indexed fields, row-based replication breaks fairly easily:

081013 17:02:59 [ERROR] Slave SQL: Could not execute Update_rows event on table test.t1; Can't find record in 't1', Error_code: 1032; handler error HA_ERR_END_OF_FILE; the event's master log master-bin.000001, end_log_pos 832, Error_code: 1032
081013 17:02:59 [ERROR] Slave: Can't find record in 't1' Error_code: 1032
081013 17:02:59 [ERROR] Error running query, slave SQL thread aborted. Fix the problem, and restart the slave SQL thread with "SLAVE START". We stopped at log 'master-bin.000001' position 682

How to repeat:
--source include/master-slave.inc

SET binlog_format = 'row';

CREATE TABLE t1 (
        `int_key` int,
        `int` int,
        key (`int_key` )
) ENGINE=myisam;

INSERT IGNORE INTO t1 VALUES (NULL, '9');
UPDATE t1 SET `int_key` = 5 WHERE `int` = 9;
UPDATE t1 SET `int` = 0 WHERE `int_key` < 9;

--save_master_pos
--connection slave
--sync_with_master

Thank you for the report.

Verified as described.

Unable to reproduce failure for 5.1-5.1.29-rc.
