1.6.4-313 loses master log info

[Ren Xiaolei]

xtrabackup-1.6.4-313.rhel5

Execute innobackupex script on a master MySQL server, got a line below:
"innobackupex: MySQL binlog position: filename 'xtrabackup', position ping 5"

similar line in backupdir/xtrabackup_binlog_info file:
"xtrabackup ping 5"

OLD version xtrabackup-1.6.3-292.rhel5 works fine. It might be a new bug introduced in 1.6.4-313

Confirmed, it's a regression introduced in 1.6.4.
