Invalid interface to SNW_SERVICE in Ubuntu 14.04

After recent/last updates I can't start/connect KebrumVPN (openvpn engine) client GUI on 14.04, here's the log from terminal:

sudo '/usr/bin/Kebrum'
Command: /usr/bin/Kebrum --server --daemon

I have noticed on Launchpad similar bugs description on previous distros from different apps. I was using this app for a long time and this happened after recent updates on May 11, 2014 if I'm not mistaken. Though I can connect to KebrumVPNs using terminal command `sudo openvpn /etc/openvpn/location1.UDP.ovpn` and it works.
