Always I want to edit a network-connection(WiFi, VPN, eth etc.) I get a log-message something like

May 2 21:39:19 mylaptop NetworkManager[925]: <info>  [1462217959.6967] audit: op="connection-update" uuid="850afb13-cf82-402c-af7a-80408324329a" name="myname1" result="fail" reason="connection.gateway-ping-timeout: can not set property: value "32497520" of type 'guint' is invalid or out of range for property 'gateway-ping-timeout' of type 'guint'"

which seems to be a false default value of a variable inside the network-manager? How to solve this problem? Is this a bug of the network-manager?

Additional information:

me@mylaptop:/etc/NetworkManager$ NetworkManager --version

After looking under /etc/NetworkManager/system-connections, I found all my connections. In every connection there is another gateway-ping-timeout, but I cannot edit this variable within the plasma network manager. So I think anywhere in the communication between the Plasma desktopapplication and the NetworkManager there is a fault.?!

This bug has been reported to KDE and they have provided a patch to the networkmanager-qt package. I am looking for people to test it. If you can install one of the following packages (one is for amd64 and the second is i386)



Please let me know if the patched package solves your problem.
