pt-slave-restart failed with Argument isn't numeric in sort at pt-slave-restart line

Hi,

I’m getting below error:
pt-slave-restart -u [user] -p[pwd] -h xxx -P 3372 --error-numbers=1032
2014-09-26T04:12:40 P=3372,h=[host],p=…,u=[user] mysql-relay-bin.003489 19453709 1032
Argument “6706958-7001820” isn’t numeric in sort at /usr/bin/pt-slave-restart line 5078.

I’ve installed percona-toolkit-2.2.10-1 [rpm]
and mysql version is 5.6.19-log [GPL] with GTID enabled.
Below are the Retrieved and executed GTID from show slave status ::

Please suggest how i can run it. as i read in new release document of percona that now it also support for GTID replication.
Thanks in advance.
