      Full error log is attached as mysql.err

      The backup datadir before prepare can be found here:
      ftp://ftp.askmonty.org/public/mdev18309-backup_before_prepare.tar.gz

      The backup log is attached as mbackup_backup.log

      To reproduce, unpack the backup datadir, adjust the path to the plugin dir and the encryption key file and run

      bin/mariabackup --prepare --target-dir=`pwd`/backup_before_prepare
      bin/mariabackup --copy-back --target-dir=`pwd`/backup_before_prepare --datadir=`pwd`/data 
      

      and start the server with

      --innodb-encrypt-tables --innodb-encrypt-log --innodb-encryption-threads=4 --aria-encrypt-tables=1 --encrypt-tmp-disk-tables=1 --file-key-management --file-key-management-filename=/home/travis/mariadb-toolbox/data/keys.txt --plugin-load-add=file_key_management --innodb-compression-algorithm=zlib --innodb-page-size=8K
      

      I have no information yet whether it affects earlier versions.
