Last night I upgraded to the following packages:
ii ldap-utils 2.4.10-2+lenny1 OpenLDAP utilities
ii libldap-2.4-2 2.4.10-2+lenny1 OpenLDAP libraries
ii libwbclient0 2:3.2.0-4 client library for interfacing with winbind service
ii samba 2:3.2.0-4 a LanManager-like file and printer server for Unix
ii samba-common 2:3.2.0-4 Samba common files used by both the server and the client
ii samba-dbg 2:3.2.0-4 Samba debugging symbols
ii samba-doc 2:3.2.0-4 Samba documentation
ii smbclient 2:3.2.0-4 a LanManager-like simple client for Unix
ii winbind 2:3.2.0-4 service to resolve user and group information from Windows NT servers
Unrelated, but I figure I'll mention it.
The upgrade from 3.0.x to 3.2.x bit me.
We have a perl script that returns a list of members of a group as follows:
my (undef, undef, $gid, $members) = getgrnam "$group";
For Samba 3.0.x $members contained a space separated list of names (eg "user1 user2 user3").
Now with Samba 3.2.x it contains the Windows domain name as well (eg "DOMAIN\user1 DOMAIN\user2 DOMAIN\user3").
It's fine, I just had to change the code to suit, but it caused some problems for a while.
Is that something that needs to be mentioned somewhere in the NEWS.Debian file or something like that?
Anyway. On to the problem at hand.
The panics are not fixed.
Here is the new panic dump from version 3.2.0 as supplied by the panic-action script:

The program is running. Quit anyway (and detach it)? (y or n) [answered Y; input not from terminal]
In the /var/log/samba/log.wb-PRY there is the following info:

The /var/log/samba/log.winbindd file didn't have panic information.
But just in case it's useful, the entries for the same time in this file were:
