Bug Description
Binary package hint: network-
When using nm-openvpn to connect to a OpenVPN server which is configured to use comp-lzo compression and the client option is _not_ configured to use comp-lzo the connection appears to be working, but actually is not. The only indication of a problem is the following line in daemon.log:
nm-openvpn[4429]: WARNING: 'comp-lzo' is present in remote config but missing in local config, remote='comp-lzo'
Steps to reproduce:
1. Set-up OpenVPN server with comp-lzo enabled
2. Set-up Ubuntu client through network manager with comp-lzo disabled
3. Connect to VPN
Actual result:
Connection appears to be up, but is not working.
Expected result:
- Network manager shows pop-up with error
or
- Network manager prompt user to enable comp-lzo and reconnect

Confirmed. This is still current even with 0.8~a~git.
Tried with SwissVPN test account, enabled LZO compression where remote doesn't enable it, VPN silently fails when traffic is sent through; works in the meantime with messages:
Dec 11 00:09:11 mtrudel-laptop nm-openvpn[4212]: Bad LZO decompression header byte: 42
This also applies to link-mtu:
Dec 11 00:09:42 mtrudel-laptop nm-openvpn[4212]: WARNING: 'link-mtu' is used inconsistently, local='link-mtu 1544', remote='link-mtu 1543'
