Damn, I have the same issue too.
Running 2.0.3.5_canary_2018-04-13 with Minio and B2 as backend.
1st, I had:
Errors: [ 2018-04-29 20:01:21 -04 - [Error-Duplicati.Library.Main.Operation.TestHandler-FailedToProcessFile]: Failed to process file duplicati-20180430T000000Z.dlist.zip.aes, 2018-04-29 20:02:12 -04 - [Error-Duplicati.Library.Main.Operation.TestHandler-FailedToProcessFile]: Failed to process file duplicati-ib24ac61eed1b4353ab726737c5997496.dindex.zip.aes, 2018-04-29 20:03:03 -04 - [Error-Duplicati.Library.Main.Operation.TestHandler-FailedToProcessFile]: Failed to process file duplicati-ba1eadafe92b04631ad00657efd2c75c1.dblock.zip.aes ]

I tried to repair DB, with the error still happen. But at least the backup was still working.
Then I tried to rebuild the DB, but now the backup failed each time with:
Unexpected number of remote volumes marked as deleted. Found 2 filesets, but 20 volumes
Any idea on how to fix this issue ?
