I fixed the problems with anydbm using the dbm module at the backend. It turns out the dbm module modifies the file name to append ".db" and my check to determine if we're opening an existing or new db just tested os.path.exists() on the filename. Well, no longer! We now perform a much better check _and_ cope with the anydbm implementation module changing too! I also fixed the backends __init__ so only ImportError is squashed.
