Commands deleting the bridges.  I checked another system which used
the Ubuntu native build and didn't see the same behavior.  The commands
recorded in the database look like they come from ifupdown.sh.

(See http://pastebin.com/C9zbNuia for full transaction history.)

# The loopback network interface

  ovs_bridge ovsbr0

Ok, will try shortly.
