[Pkg-samba-maint] Bug#570099: samba: smbd segfaults when accessing printing preferences on XP client

[EmTeedee]

Package: samba
Version: 2:3.4.5~dfsg-2
Severity: normal

When trying to set printing preferences for network printers, the smbd
server
process segfaults. This is reproducible every time. We're using cups to
print:
ii  cups                   1.4.2-4           Common UNIX Printing System(tm)

This particular problem did not exist in samba 2:3.2.5-4lenny8, but we
upgraded
due to problems joining the domain with Windows XP SP3 clients (which works
perfectly fine with this version).

The printing preferences eventually do come up, but the user's smbd
processes
keep segfaulting until the dialog is closed.

Apart from being annoying and generating lots of panic reports, it also
causes
problems with open files.

Attached are a strace and gdb log, I couldn't get them from the same
process,
but they are caused by the same action.

Regards,
        Tobias
