Bug Description

Hello
I have relatively simple openvpn connection config

[connection]
id=developer-vpn-la
uuid=3e6fc95d-0bc0-4118-a00a-7c6f3852c2fd
type=vpn
gateway-ping-timeout=71

service-type=org.freedesktop.NetworkManager.openvpn

[ipv4]

method=auto

[ipv6]

dns-search=
method=auto

I want to add 'never-default=true' option via GUI (KDE) but it can't be saved. Error in logs:

I receive the message "connection.gateway-ping-timeout: can not set property: value "xxxxxxxx" of type 'guint' is invalid or out of range for property 'gateway-ping-timeout' of type 'guint'" almost on every change of network connection properties

Hi there,

the problem is even worse. Even the simplest network connections fail most of the time, as the value to be set for connection.gateway-ping-timeout varies randomly.

Steps to reproduce the problem (almost) consistently on Kubuntu Xenial are:

# Right-click systray/Networks
# Click Configure Network Connections
# In the Connection Editor, click "Add+".
# Click Wired Ethernet.
# Click OK
# If the connection really get added, you've been lucky: A plausible number was randomly set for connection.gateway-ping-timeout.
# Either retry from step 3 until adding fails or edit your new connection, change the name and click OK. The most tries I ever needed to get the error message was 3 times.

And please take a closer look at the config of the original bug reporter: "connection.gateway-ping-timeout=71" ist explicitly set, but NM tries to set a ridiciously large value which is not in the original config!

Regards,
Jochen
