segmentation fault connecting to Samba PDC

[Eric the Fruitbat]

Hello.  I'm a Samba newbie who is managing a mixed network of Windows and Linux 
machines over a VPN, with a Linux PDC handling domain logins, as follows:

	   network A				 network B
	  192.168.1.0				192.168.3.0

192.168.1.2 -----.                                     .----- Win 98
 Mandrake/2.2.14 |                       PDC "badger"  |
 Samba 2.0.6     |-- gateway --- ppp --- 192.168.3.1 --|
                 |                       SuSE/2.2.7    |----- Win 95
192.168.1.20 ----'                       Samba 2.0.6   |
 NT 4.0 sp3                                            |
                                                       `----- Win 95

Previously, when I was using development versions of Samba for the PDC, 
connection from the machines in A worked well, and connections from B 
(especially the 95 boxes) would sometimes fail or perform poorly.

In an effort to straighten everything out once and for all, I installed 
the latest official release onto the PDC and upgraded 192.168.1.2, as 
above.  Now connections from B work flawlessly, much to the relief 
of users on that end, but connections from A fail outright.

More specifically, although from 192.168.1.2 the command

% smbclient -L badger -Ueric%password

produces the correct list of shares, servers, and workgroups, the command 

% smbclient '\\badger\eric' -Ueric%password

produces a segfault.  When run from the PDC itself the second command 
produces the smb: \> prompt, as expected.

The NT machine has a similar problem:  it can see the entire network in 
its network neighborhood, and can browse machines that have public-access 
shares, but it can't log into the domain.  At least, the problem seems 
similar to my unlettered mind.

Can anyone shed light onto what might be going on here?  When I run the 
smbclient command with -d9, everything seems to work fine up to "tconx 
ok", and then it just ups and dies, but I don't really know how to read 
the debug output so I can't be sure.  Any help is greatly appreciated, or 
if there's some documentation that already deals with this issue I'm happy 
to check it out.  Thanks in advance.
