Redundant argument in printf at /usr/bin/pt-table-checksum

While **pt-table-checksum** seems to work well for most tables, a few of the big ones get this: > Error checksumming table mydb.mytable: Redundant argument in printf > at /usr/bin/pt-table-checksum line 8106. Versions: > pt-table-checksum 2.2.11 Servers (MariaDB acting as both slave to MySQL and master to another MariaDB, happens in both cases): > mysql Ver 14.14 Distrib 5.6.36, for Linux (x86_64) using EditLine > wrapper mysql Ver 15.1 Distrib 10.1.24-MariaDB, for Linux (x86_64) > using readline 6.3
