samba - Dec 2002 - How to disable "net ads join" verbose and why it core dumps

This is with samba-3.0a20 on freebsd.  I used 3.0a19 on another different 
freebsd version before and it worked.

Run the command "net ads join" shows:
# net ads join

Segmentation fault (core dumped)

I have run "kinit" successfully.  Questions are: How do I make the net
command to not show all these messages, and why it would do a core dump?

Thanks in advance.
