GRANT ALL produces different results on master and slave

[Alex Yurchenko]

The following script:
======================================
HOST=127.0.0.1
PORT=3305
USER=root
PSWD=rootpass

mysql -u$USER -p$PSWD -h$HOST -P$PORT << EOF

CREATE DATABASE linkdb;
USE linkdb;
CREATE USER 'linkbench'@'%' IDENTIFIED BY 'linkpass';
GRANT ALL ON linkdb TO 'linkbench'@'%'

EOF
=====================================

results in

INSERT INTO `tables_priv` VALUES ('%','linkdb','linkbench','linkdb','root@localhost','2013-05-01 04:48:24','Select,Insert,Update,Delete,Create,Drop,References,Index,Alter,Create View,Show view,Trigger','');

on master and

INSERT INTO `tables_priv` VALUES ('%','linkdb','linkbench','linkdb','','2013-05-01 04:48:24','Select,Insert,Update,Delete,Create,Drop,References,Index,Alter,Create View,Show view,Trigger','');

on slave.

Note inconsistency in the fifth column. It also may well be that the sixth column can also be inconsistent if the query timing is wrong.
