Unless I'm misreading the code, it's a race-condition. mash creates the
metadata for all architectures in parallel. One process per arch. The
createrepo checksum cache file I/O  is not protected against concurrent
access. With odd timing, it can happen that one process reads an empty
checksum file that has just been opened for writing by another process.
Give it a try. Add a safety check after reading a checksum file.
