[Pkg-samba-maint] Bug#476334: more segfaults

[Brian May]

Hello,

We seem to  be getting random and unpredictable segfaults again that 
look very similar to what I reported before.

This time the client computer is a "Windows Vista (TM) Ultimate 6.0" 
system (identified with smbclient).

I upgraded Etch to Lenny in the hope it would solve the problem, but so 
far it seems that
Samba 2:3.2.0-4 has the same issue.

Note I applied the following patch to fix a problem with printing:
<https://bugzilla.samba.org/attachment.cgi?id=3423&action=view>.
I will install the pristine Debian code again and see if the problem 
reoccurs.

The details are below. This looks similar, but not identical, to the 
stack trace I got before.
