This is not a sysbench bug. This is a difference between regular MySQL server and a Galera node. The latter may fail to execute queries with a variety of errors due to conflicts, nodes getting into desync state, etc.
Both sysbench 0.4 and 0.5 branches now support the --mysql-ignore-errors option to, well, ignore this kind of Galera-specific errors.
