Bug 310886

Application: kcmshell4 ()
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-33-generic x86_64
Distribution: Ubuntu 12.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:

The network manager crashed when importing OVPN file from ipredator.se trying to set up a VPN. It crashes reliably, every time. Full trace included. 

Content of ovpn file:
--------
client
dev tun0
proto udp
remote pw.openvpn.ipredator.se 1194
resolv-retry infinite
nobind

auth-user-pass

ca /path/to/openvpn/config/keys/IPredator.se.ca.crt

tls-client
tls-auth /path/to/openvpn/config/keys/IPredator.se.ta.key
ns-cert-type server

keepalive 10 30
cipher AES-256-CBC
tls-cipher TLSv1:!ADH:!SSLv2:!NULL:!EXPORT:!DES:!LOW:!MEDIUM:@STRENGTH
persist-key
persist-tun
comp-lzo
tun-mtu 1500
mssfix
passtos
verb 3
--------

By the way, I can now see that "/path/to/openvpn/config/keys/" is wrong, and probably that's why it's not accepted, but this should most certainly not segfault, just give an error message.

Please fix! Thx!

Mate

The crash can be reproduced every time.
