Applying incremental backup using xtrabackup 2.0.3 fails when innodb_data_file_path = ibdata1:2000M;ibdata2:10M:autoextend is set in [mysqld]

If in your [mysqld] section of my.cnf, this is set:
innodb_data_file_path = ibdata1:2000M;ibdata2:10M:autoextend

innobackupex cannot apply incremental backup:
