pdbedit segmentation fault on machine account

After upgrade from samba 2.2.8a to 3.0.1, I was getting "machine account
SunOS bonsai 5.8 Generic_108528-22 sun4u sparc SUNW,Ultra-5_10
gcc (GCC) 3.3.1
I did a pdbedit -Lv to check the account, and got segmentation fault.
I'm thinking these might be related.
Samba is using the smbpasswd file backend. (In a test install with ldap
backend, no problem listing machine accounts with pdbedit)
Here's the backtrace:

This is the account in the smbpasswd file and on the system:
root at bonsai# grep om-679 ../private/smbpasswd
root at bonsai# getent passwd om-679$
Using samba 3.0.2, when Imove the client machine to a work group, then a
back to the domain, login succeeds. Works OK for one machine, but hey,
we got plenty. Still pdbedit segfaults. User accounts are fine. Logging
in from Win98 is fine, connecting to the share as user/pass after
logging in to the local machine is fine. Domain login fails with no
account for machine. Roll back to 2.2.8a works fine.
Anybody else think this is related? Suggestions? How can I trace what's
failing the machine login?
