Description Valdas 2016-04-23 13:50:48 UTC 
If I change something in Connection settings (f.e. MTU, gateway) through NetworkManager applet and close dialog then error message popups and I lost all my changes.

Excerpt from error message: connection.gateway-ping-timeout: can not set property: value...

I attaching screenshot of message;

Snippet from .xsession-errors:

QXcbConnection: XCB error: 2 (BadValue), sequence: 12829, resource id: 106954756, major code: 142 (Unknown), minor code: 3

D-Bus call: "org.kde.Spectacle" : "/" : "StartAgent" : ()

I encounter this when installed Kubuntu 16.04 (freshly). This happens even in LiveCD session.

Reproducible: Always

Steps to Reproduce:
1. right click on Connection icon and choose "Configure connections...";
2. create or edit existing connection;
3. change something, f.e. fill inn fixed IP, DNS, gateway, or change MTU;
4. close dialog -> error message;
5. reopen last edited Connection -> all changes reverted to default

This is caused by latest NetworkManager and should be fixed in upcoming frameworks release, see:

Git commit 93faf9ec94826c5d753aa090313472800ee41b86 by Jan Grulich.

ConnectionSettings: Initialize gateway ping timeout

NM 1.2.0 is really strict about what we send when adding or updating connection

Comment 7 Ovidiu-Florin BOGDAN 2016-05-09 09:23:34 UTC 
What is the frameworks version we should expect this fix to be in?
Comment 8 Jan Grulich 2016-05-09 11:29:24 UTC 
It should be already in KDE Frameworks 5.21 and if not then definitely in 5.22 which is going to be released this week.
