Scenario:

1. Start the DB server and generate some initial data

2. Several sessions run some DML mix concurrent.

3. During 2. is ongoing run loops consisting of

    3.1 mariadb-backup --backup  to some location A

    3.2 mariadb-backup --prepare on location A

    3.3 Start a DB server on location A and check the integrity of the data

3.2 fails in one of these loops fails with

1298 tests with that scenario were executed and 84 of them failed with that error.

Hence I set the priority to "Blocker".

The rr traces above belong to some RQG test which fiddles with partitioned and non partitioned tables. Other tests which do not use partitioned tables show the same problem.
