Hi,
I've managed to correct this error of mine, using the correct backend name,
that is, *leveldb_mult* instead of *leveldb*
Now I have another problem: the python client returns no error, the riak
log is also clean.
But I can find the created bucket when I run buckets?buckets=true
Seems to me it isn't being persisted, I'm investigating.
