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

- Opened the Networking system settings module from the Plasma widget
- Made modifications to a network
- Clicked to change to a different network
- On the pop-up asking to save my changes, I chose to save changes
The crash happened before the other network's settings panel displayed and after the dialogue window closed.

-- Backtrace:
Application: System Settings Module (kcmshell5), signal: Segmentation fault
