Cannot view archfs through samba

[GoogleCodeExporter]

What steps will reproduce the problem?
1. create a samba share that contains the mounted archfs
2. mount the previous samba share
3. cd to the mounted share

What is the expected output? What do you see instead?
The files/folders inside the share but I see nothing (only . and .. entries)

What version of the product are you using? On what operating system?
Linux Ubuntu 10.04.3 LTS 2.6.32-35-generic
smbd --version: Version 3.4.7
archfs -v: version 0.5.3

source folder shows 0.5.4 version and is patched with these:
archfs.c
    args[0] = argv[0];
    args[1] = mount;
    args[2] = strdup("-oallow_other");

    return fuse_main(3, args, &operations, NULL); 

revisions.c
    if (stats->type == S_IFDIR){
        stbuf->st_mode = stats->type | 0755;
        stbuf->st_nlink = 2;
    }
    else{
        stbuf->st_mode = stats->type | 0444;
        stbuf->st_nlink = 1;
    }

Please provide any additional information below.

This is still an issue using rdiff-backup-fs 1.0.0.

Using "--debug 4" with rdiff-backup-fs the output is the same when using 
samba/cifs or sshfs (where it works).

I have filed this bug in Launchpad for Ubuntu at: 
https://bugs.launchpad.net/ubuntu/+source/rdiff-backup-fs/+bug/1011315

That's the output with debug 4:

these lines seems rellevant to me:

   unique: 3, error: -38 (Function not implemented), outsize: 16
unique: 4, opcode: LOOKUP (1), nodeid: 1, insize: 42

Same problem here. Ubuntu 12.04 . Any advice?

Here are three patches that work for me to solve that issue.

Please note that I am *not* a C-developer and know only partially what I did.
But hey, it works :-)

I appreciate any comments and / or improvements,
