Network Manager client fetches the basic information from Network Manager, caches it and updates the cache whenever it receives the signal. So, create only a single instance of it and reuse it. Reusing from different threads is apparently fine because the underlying DBusConnection is a singleton[1] that is meant to be used from multiple threads. The glib main loop context that is related to the client must run even after the network manager client object goes away[2]. So, create the network manager client instance from a thread that continues to run the glib main thread. This fixes an infrequent crash when accessing network manager page. The problem was reproducible from very early version of Network Manager and FreedomBox. However, in more recent versions of NetworkManager 1.20 with recent DBus changes in FreedomBox, the problem is more prominent. The problem reduces to a simple warning in NetworkManager 1.22. Closes: #1724 Closes: #382 Tests: - Reproduce the problem by accessing the networks app index page repeatedly. - Create a simple test case file to reproduce the problem and ensure that the fix works there. - On Network Manager 1.20 repeatedly access the networks app index page and create/delete/activate/deactivate/show connections. - On Network Manager 1.22 repeatedly access the networks app index page and create/delete/activate/deactivate/show connections.

FreedomBox Service (Plinth)
The core functionality and web front-end of FreedomBox.
Description
FreedomBox is a community project to develop, design and promote personal servers running free software for private, personal communications. It is a networking appliance designed to allow interfacing with the rest of the Internet under conditions of protected privacy and data security. It hosts applications such as blog, wiki, website, social network, email, web proxy and a Tor relay, on a device that can replace your Wi-Fi router, so that your data stays with you.
This module, called FreedomBox Service and also know as Plinth, is the core functionality and web interface to the functions of the FreedomBox. It is extensible and provides various applications of FreedomBox as modules. Each module or application provides simplified user interface to control the underlying functionality. As FreedomBox can act as a wireless router, it is possible to configure networking. It also allows configuration of basic system parameters such as time zone, hostname and automatic upgrades.
You can find more information about FreedomBox Service (Plinth) on the Plinth Wiki page, the FreedomBox Wiki and the FreedomBox Manual.
Getting Started
To have a running FreedomBox, first install Debian (Buster or higher) on a clean machine. Then run:
$ sudo apt install freedombox
Full instructions are available on FreedomBox Manual's QuickStart page.
For instructions on running the service on a local machine from source code, see INSTALL.md. For instructions on setting up for development purposes, see HACKING.md.
