Details

Description:
It seemingly happend with the latest update, since after update to 43.1 everything worked fine. Attempt to add any new VPN connection in Gnome Control center fails with the error

Additional info:
Error message:
(gnome-control-center:10404): GLib-GIO-ERROR **: 23:51:33.722: settings object created with schema 'org.gnome.nm-applet.eap' and path '/org/gnome/nm-applet/eap/2b7e5573-d9eb-4906-82ca-674e00e54fca/', but path '/org/gnome/nm-applet/eap/' is specified by schema

All packages are the latest as of NOV 9, 2022, 00:00 AM GMT +03:00
Gnome Control Center version is 43.1-2
libnma-gtk4 version: 1.10.4-1
libnma version: 1.10.4-1
networkmanager-pptp version: 1.2.10-2
networkmanager version: 1.40.2-1

Steps to reproduce:
1. Open gnome-control-center
2. Go to Networks Tab
3. Click "+" On VPN list
4. Choose any (tested PPTP and OpenVPN)
5. Enter minimum info (server address for PPTP) to make "Add" button available
6. Click Add
7. That's the moment when control center halts for a second and shuts down with error

It behaves identically on 2 different PCs (laptop and desktop).
This task depends upon

Here is a coredump for gnome-control-center.
Debian Testing appears to use the same version and it works fine, so I don't think that's an upstream bug. I'll try my best to provide any info or help with testing regarding the bug since it's in my best interest that this is fixed ASAP.

Also forgot to mention - both machines tested are brand new Arch installs (did about 2 hours ago for both).

> Here is a coredump

Where? Forgot to attach? But do not worry..

We need a backtrace with debug symbols. I just reproduced this in a VM and will attach 2 backtraces. Once is with "bt" and the other is with "bt full". Someone who cares about this should probably report it upstream.
   gdb.bt.txt (9 KiB)

This same crash also happens for me with nm-connection-editor, so it may not be gnome-control-center specific.

Yeah, can also repro with nm-connection-editor so I suppose the bug is in "libnma". Attaching another trace.

For now rolling back libnma, libnma-common and libnma-gtk4 to version from October 25 fixes the issue. Here is a command (using Arch archive) for convenience in case someone stuck:

sudo pacman -U https://archive.archlinux.org/packages/l/libnma/libnma-1.10.2-2-x86_64.pkg.tar.zst https://archive.archlinux.org/packages/l/libnma-common/libnma-common-1.10.2-2-x86_64.pkg.tar.zst https://archive.archlinux.org/packages/l/libnma-gtk4/libnma-gtk4-1.10.2-2-x86_64.pkg.tar.zst

It doesn't mess with any other packages so rollback is safe to do imo.

Toolybird, I've tried to add 15+ MiB coredump using the button that explicitly says 'max 2 MiB', because of course I did. I'll try to report upstream today and post info here. If anyone would do that before me, please also post here.
