Does it happen on all incremental backups taken with 2.0.1 and restored with 2.0.2 or just some particular ones?
Looking at the relevant source code, since there is no "xtrabackup: page size for %s is %lu bytes\n" in the output, it must be either get_meta_path() or xb_read_delta_metadata() failure. Neither of which has changed between 2.0.1 and 2.0.2, this needs further analysis.
