Bug Description

I think this is related to the update of network-manager to 1.4.4-1ubuntu3.1.

Now I can't connect to my VPN using network-manager-openvpn because it fails with an error about an invalid cipher.

The relavant error found int the log are:
juin 21 18:26:36 titan nm-openvpn[6585]: Error: pushed cipher not allowed - aes-128-cbc not in AES-128-CBC or AES-256-GCM:AES-128-GCM
juin 21 18:26:36 titan nm-openvpn[6585]: OPTIONS ERROR: failed to import crypto options
juin 21 18:26:36 titan nm-openvpn[6585]: ERROR: Failed to apply push options
juin 21 18:26:36 titan nm-openvpn[6585]: Failed to open tun/tap interface

Given the error it seems to be a problem of bad case in the code ??

That error happened once and disappeared to never be shown again for now.
