Python bindings failure when MasterServer=BackendServerIP6

[Bill Meek <keemllib@…>]

Running on: v0.25pre-4589-gf4a1079.

To duplicate, create this fragment of a python script.

#!/usr/bin/env python
from MythTV import MythBE
be = MythBE()

Executing the above results in:

Traceback (most recent call last):
  File "/home/bill/bin/test.py", line 3, in <module>
  be = MythBE()
    File "/usr/local/lib/python2.7/dist-packages/MythTV/mythproto.py", line 97, in __init__
    self.host)
    MythTV.exceptions.MythDBError: Could not find setting 'BackendServerIP' on host 'fd00::f00'

The following allows the script above (and find-orphans) to run:
