samba bug (?): 3.0.0 nmbd panic: internal error

[nosp]

I changed network interfaces (from eth0 to eth1) and forgot to update my
"Interfaces = eth0 lo" line in smb.conf.  smbd didn't complain much but
nmbd "panic"ed with an "internal error."  It's my fault of course but
figured I should raise it in case anyone else runs across it.  I'll
submit it to the samba people for cleanup.
