Package: nm-connection-editor
Version: 1.36.0-3+b1
Severity: important

Dear Maintainer,

I cannot view or edit the settings of a VPN of type VPNC anymore in nm-
connection-editor and also not in gnome-control-center. Fortunately the
configured VPN is still usable, connections yet succeed.


In nm-connection-editor the respective tab is just empty, see
attachment "nm-connection-editor 2025-03-15 18-22-40.png".

The messages emitted to the console are

$ LANG=C.UTF-8 nm-connection-editor 

** (nm-connection-editor:7751): WARNING **: 18:21:10.483: Could not load editor VPN plugin for “org.freedesktop.NetworkManager.vpnc” (cannot load factory nm_vpn_editor_factory_vpnc from plugin: /usr/lib/x86_64-linux-gnu/NetworkManager/libnm-vpn-plugin-vpnc-editor.so: undefined symbol: nm_vpn_editor_factory_vpnc).

In gnome-control-center the respective tab is empty besides the error
message "unable to load VPN connection error", see attachement "gnome-
control-center 2025-03-15 18-01-11.png".

There are no logs emitted to the console about this
