Yes, it looks like it's an error on my part in
debian/patches/replace-vendored-hash-functions.patch. The old MD4 code
expected to be given message size in bits rather than bytes as the new
MD4 functions expect, hence the mismatch.

I'm going to spin up a test environment to make sure it's right before I
upload. I'm also chasing a suspiciously similar sounding bug (891020)
that I'd like to squash in the same upload.

Cheers,
Chris
