+++ This bug was initially created as a clone of Bug #1233139 +++

Description of problem:

        if (gf_uuid_compare (stbuf.ia_gfid, tmp_loc.inode->gfid)) {
        gf_msg (this->name, GF_LOG_ERROR, 0,
                        DHT_MSG_GFID_MISMATCH,
                "%s: gfid different on the target file on %s",
                        tmp_loc.path, dst_node->name);
                ret = -1;
        local->op_errno = EIO;
                goto out;
    }

        dst_node = dht_subvol_get_cached (this, tmp_loc.inode);

dst_node->name is accessed in the log, but dst_node is assigned later on.
