I saw the same error myself when integrating that patch into my series. I discussed it more in [1], but the failure is basically caused by the midx code using the_hash_algo even when operating in a different repository via --object-dir. If the_hash_algo doesn't match (as is the case when using `--object-dir` to point at a SHA-256 repository when invoking the builtin from a repository using SHA-1 or outside of a repository altogether), then we'll fail when trying to open the pack indexes.
