Good call.

Yes, this is to be expected.  The "040" prefix identifies it as a directory,
where the "120" prefix identifies symbolic links.  Both cases drop into the
"grab the inode and do more" codepath (which is good, this is expected).

I would say the next thing to check is what happens here:
    /* decode symlink type */
    fstat( fd->unix_fd, &st );
    is_dir = S_ISDIR(st.st_mode);
So, after that I would put something like this:
    if (strstr(fd->unix_name, "The.Elder.Scrolls.V.Skyrim/Data")) {
        fprintf(stderr, "After Path: '%s', Data mode: %06o\n", fd->unix_name,
st.st_mode);
    }
