[Samba] Samba 3.2.6 upgrade -> smbd panic in printing.

I updated the server to that same Centos 5.2 level just before upgrading
Samba to 3.2.6, as part of a maintenance window. So I am unsure of any
relation. But ... in desperation when having the issue I downgraded Samba
to 3.2.4, the version I had at hand. The problem persisted.

Yesterday I did a full regression on Samba, glibc, cups and kernel
version. Now the problem is gone.

Not enough evidence to prove causation, true. That server being a
production machine means I can't use it for testing any longer,
unfortunately.
