I noticed there hasn't been an update on this issue yet and the last patch for 6.12 was released on 8-9-2018.  We have a customer that's migrating from a different DM system that has run into this when cleaning up index entries from the import.  If it's any help here is the associated error from the Platform Error Log:

New entry --------------------------------------------------------------------------------

System.NullReferenceException: Object reference not set to an instance of an object.
