Gutsy nautilus cannot browse samba shares

Hello all,
Oh man... I've been troubleshooting this since last night. Gutsy fully updated.
I setup a samba shares on my notebook. Testing it with smbclient command,
result is OK:
root@voyager2:~ # smbclient -L localhost
Password:
Domain=[MARS] OS=[Unix] Server=[Samba 3.0.26a]

        Sharename Type Comment
        --------- ---- -------
        print$ Disk Printer Drivers
        public Disk Untuk public share
        IPC$ IPC IPC Service (voyager2 server (Samba,
Ubuntu))
        c87 Printer c87
Domain=[MARS] OS=[Unix] Server=[Samba 3.0.26a]

        Server Comment
        --------- -------
        VOYAGER2 voyager2 server (Samba, Ubuntu)

        Workgroup Master
        --------- -------
        MARS VOYAGER2

I can also connect to the share:
mount -t smbfs //localhost/public /mnt

But, I cannot browse the list using Nautilus. It's able to look at MARS, but
when I click it errors "Cannot display content...."

So, finally, I'm testing by installing Centos using vmware, open it's
Nautilus, and voila! It connects right away to it (the shares on my Ubuntu
samba). So, I assume the flaw is with Gutsy's Nautilus?

Curiously, if I'm using the "Connect to server" menu from Nautilus, it
connects without problem. It can also then can browse the share from network.
But, when I umount the connection, some time later it will error again about
cannot display the content of ...

Additional info:
When clicking on the workgroup MARS, it then error "Cannot display the content
of ..."
I notice that the window title of Nautilus says "Mars on Mars", shouldn't
it "Voyager2 on Mars"?

Additional info:
I'm testing using xsmbrowser, and it works perfectly. So it's got to be Nautilus?
