[Bug 64719] Regression after #59690: Wireless conf gets corrupted after static IP conf

[Stéphane Démurget]

Public bug reported:

After the upload of the new system-tools-backends (1.9.7-0ubuntu1) and
liboobs (0.6.0-0ubuntu1) that fixed [#59690 [network-admin] Static IP
configuration doesn't adds the default route to the gateway], I get the
following behavior.

If I only change the gateway on my wireless connection (eth1) to
192.168.0.200, it is correctly changed in my /etc/network/interfaces
file, but I've got no more WiFi connectivity because two fields are
overwritten. I get :

wireless-essid 192.168.0.200
wireless-key s:1

I'm used to have a correct network name "ubuntu" and a correct wireless
key too.
