Neo4j 2.1.2 incremental backup fails but full backup succeeds

We recently upgraded our database from 2.0.1 to 2.1.2 (Enterprise) using the explicit upgrade procedure.

When trying to take a backup post-upgrade, full backups succeed, but incremental backups fail.

When running this command the first time, it succeeds:

~/neo4j-enterprise-2.1.2/bin/neo4j-backup -from single://127.0.0.1 -to /mnt/backups/neo4j-test-backup

Running it a second time gives the following error:

Performing backup from '127.0.0.1'

Any help/workarounds are appreciated.

Update: The same behavior persists after upgrading to 2.1.3

Could you please check again in the issue is resolved with 2.1.4? I darkly remember a resolved issue regarding incremental backups.
