I found a possible cause. dht code ineed takes care of the directory case:
        if (IA_ISDIR (oldloc->inode->ia_type)) {
                dht_rename_dir (frame, this);
        } else {
                local->op_ret = 0;
                dht_rename_create_links (frame);

But if I add a log for oldloc->inode->ia_type, I can see it is IA_IFLNK
and not IA_IFDIR: this checks for the symlink instead of checking the 
symlink target, therefore it fails to correctly detect it is a directory.
