Can't reproduce the bug. The following script perfectly works after installing python-rhash and librhash0:
--- start of test_rhash.py ---
import rhash
hasher = rhash.RHash(rhash.CRC32, rhash.MD5)
hasher.update('Hello, ')
hasher.update('world!')
hasher.finish()
print hasher.HEX(rhash.CRC32)
print hasher.hex(rhash.MD5)
--- end of test_rhash.py ---
signature.asc
Description: OpenPGP digital signature
