Comment 2 for bug 1092593

I have 3 Virtual machines:
c1:
[mysqld]
server_id=1
innodb_file_per_table
log-bin=mysql1_binlog

c2: slave of c1, donor for c3, future master of c3
[mysqld]
server_id=2
innodb_file_per_table
log-bin=mysql2_binlog
relay-log=mysql2_relaylog
innodb_recovery_update_relay_log=1
innodb_flush_log_at_trx_commit=0
log_slave_updates

c3: new server,
[mysqld]
server_id=3
innodb_file_per_table
log-bin=mysql3_binlog
relay-log=mysql3_relaylog
innodb_recovery_update_relay_log=1
innodb_flush_log_at_trx_commit=0

Steps to reproduce:
1) setup c1 with single innodb table
2) setup replication from c1(master) to c2(slave)
3) on c1 insert rows:
start while true ; do mysql test -e 'insert x values(1000);' ; done
4) c2, send kill -9 to mysqld_safe & mysqld
5) copy /var/lib/mysql from c2 to c3
6) close connections via tcp 3306 from c3 to c1
7) start mysql on c2
8) start mysql on c3
9) on c3: stop slave; change master (not working) ; reset slave;change master; start slave;
9) check on c3 if replication is up&running
10) on c3 kill -9 on mysqld pid
11) replication is not working now on c3, because it wont to use relay log names from c2.
