I actually forgot to check if the dst checksum file exists before trying to delete it.

> Rename will move the src file and its crc *if present* to the destination.  If the src
file has no crc, but the destination already exists with a crc, then src will be associated
with the old file's crc.  Subsequent access to the file will fail with checksum errors.
