samba - Jul 2005 - [PROBLEM] Samba > 3.0.11 and the xp-missing-files patch

I've such a strange observation:

For the 3.0.11 version (and below?) there is a patch named
xp-missing-files.patch, which I've got from a Debian distro (but as I
understand, it's not the Debian's one - it's some Samba's
internal
work).  And that Samba whith this patch is ok - XP sees all the files
exported by Samba.

Then, since 3.0.12, there no more this patch - as it have been
superceded by some code which is just already in.  And that Samba, as
well as 3.0.13 and 3.0.14a, isn't ok - XP Pro SP1 doesn't see any one
file at all.  It sees the shares themself only.

Have anybody met the same problem?  And any help is appreciated.

Thanks in advance.
