The linked bug with xtrabackup is actually not related to the bug encountered here. A more relevant bug may be:

https://bugs.launchpad.net/percona-xtrabackup/+bug/1250643

Is it possible to get more information on the versions of mariadb and xtrabackup in use at the time?
Has this been encountered multiple times in multiple environments, or was this a single occurrence?
Have we ever been able to replicate it?
