panic when rejecting registration requests

[Bethany Jane]

Another, I assume unrelated, problem that we're seeing is that samba
panics every time the nmbd server rejects a registration request. 

Go ahead and check out what the logs indicate, and if you have any advice,
please tell me.  I've already submitted this to samba-bugs because that's
what they say to do for these errors.

-----------NMB Log Level 3------------
*Initial registration:*
wins_process_name_registration_request: Unique name registration for name DEFAULT<03> IP 134.10.25.169
add_name_to_subnet: Added netbios name DEFAULT<03> with first IP 134.10.25.169 ttl=518400 nb_flags= 0 to subnet WINS_SERVER_SUBNET

*A refresh from a different IP, which Samba ignores:*
wins_process_name_refresh_request: Name refresh for name DEFAULT<03> IP 134.10.25.46
wins_process_name_refresh_request: Name refresh for name DEFAULT<03> with IP 134.10.25.46 and is IP is not known to the name.

*Another registration, a release, and a confirmation, all from the original IP:*
wins_process_name_registration_request: Unique name registration for name DEFAULT<03> IP 134.10.25.169
wins_process_name_release_request: Unique name release for name DEFAULT<03> IP 134.10.25.169
add_name_to_subnet: Added netbios name DEFAULT<03> with first IP 134.10.25.169 ttl=518400 nb_flags= 0 to subnet WINS_SERVER_SUBNET

*Lots of releases from that original IP:*
wins_process_name_release_request: Unique name release for name DEFAULT<03> IP 134.10.25.169
wins_process_name_release_request: Unique name release for name 4AXG3<03> IP 134.10.25.169
wins_process_name_release_request: Unique name release for name 4AXG3<00> IP 134.10.25.169
wins_process_name_release_request: Group name release for name WORKGROUP<00> IP 134.10.25.169

*Another registration from that original IP:*
wins_process_name_registration_request: Unique name registration for name DEFAULT<03> IP 134.10.25.169
add_name_to_subnet: Added netbios name DEFAULT<03> with first IP134.10.25.169 ttl=518400 nb_flags= 0 to subnet WINS_SERVER_SUBNET

*A completely different IP tries to register, the NMB server rejects it*
*and then crashes.  Not real cool.*
wins_process_name_registration_request: Unique name registration for name DEFAULT<03> IP 134.10.22.20
wins_register_query_success: Original client at IP 134.10.25.169 still wants the name DEFAULT<03>. Rejecting registration request.
