Contains an openvpn config file and a crt file

plasma-nm fails to correctly import settings from an openvpn config file. Specifically it doesn't correctly import the security settings in the advanced properties. Connecting to the VPN server through the widget fails afterwards.

PREPARATION FOR REPRODUCING THE BUG

Download the two attached files from this bug report and put them in the same folder

STEPS TO REPRODUCE THE BUG

1. Open the "Networks" widget from the Task Manager by clicking on the widget (the widget's icon on the Task Manager is a wifi-symbol on most systems)

2. Click the "Configure the network connections..." in the top right of the widget window

3. Click the "Add new connection" in the bottom left of the new window

4. Select the "Import VPN connection..." from the bottom of the list and click the "Create" button

5. Browse to the file "UK London.ovpn" and click the "Open" button

6. Click the "No" button in the "Copy certificates - System Settings Module" window that pops up

7. Fill in a random username and password in the text fields "Username" and "Password" in the "Connections - System Settings Module" window

8. Click the "Apply" button in the same window

9. Open the "Networks" widget from the Task Manager

10. Click the "Connect" button next to the VPN connection "UK London"


EXPECTED RESULT

Connection to the VPN server is established (given that a valid username and password are provided)

ACTUAL RESULT

The procedure fails silently and without any GUI indication of failure at all. The command "journalctl -u NetworkManager -b 0" in a terminal shows the following lines in the end of the log file:

WORKAROUND

1. Select the VPN connection in the "Connections - System Settings Module" window (open it by clicking the top right button in the widget)

2. Click the "Advanced..." button

3. Click the "OK" button in the new window

4. Click the "OK" or "Apply" button in the "Connections - System Settings Module" window

WORKAROUND RESULT

Now you can connect to the VPN server through the VPN connection in the widget. The workaround procedure clearly overwrites faulty values that were written during the importing of data values from the config file.
