Thanks @christophershirk for the bug report!
In fact, it is very unfortunate that rustic does not show the defect file in the repository here.
You can manually search for files smaller than 16 bytes and remove them manually.

I think in rustic we should change the following things:

• improve the error message in this case to show the defect file
• improve the repair command to allow removing such defect files
