 I was using a BIND 10 server with an old (pre-2011-05-17) configuration.
 It has a "master_addr" for all of Xfrin, instead of per-zone.

 I was unable to commit my database changes because of that:

 {{{
 > config commit
 Error: unknown item master_addr
 Configuration not committed
 }}}

 Here is the old configuration:

 {{{
 shane at madras:/opt/bind10/var/bind10-devel$ cat b10-config.db
 {"Xfrin": {"master_addr": "85.17.60.159"}, "version": 2,
  "Auth": {"listen_on": [ { "address": "85.17.60.232", "port": 53 } ]}}
 }}}

 So I decided to remove the offending legacy configuration, with these
 results:

 {{{
 > config unset Xfrin/master_addr
 Traceback (most recent call last):
   File "/usr/lib/python3.1/cmd.py", line 213, in onecmd
     func = getattr(self, 'do_' + cmd)
 AttributeError: 'BindCmdInterpreter' object has no attribute 'do_config'

 During handling of the above exception, another exception occurred:
