Since a few I've reported this failure of NetworkManager
https://bugzilla.opensuse.org/show_bug.cgi?id=1081430
I've 100% segv if I try to connect to any openvpn defined connection (using plain openvpn --config work perfectly).
I'm using plasma5 (xorg with nvidia) as main desktop. Anybody can help me to bi-sect where the problem is located ?
