bug#63154: Settings schema 'org.gnome.nm-applet.eap' is not installed

[Steven Roose]

Recently did a system upgrade and getting that error now when entering 
password for a new wifi network. It also kills the networkmanager applet.

Full error:
(nm-applet:2051): GLib-GIO-ERROR **: 19:06:02.763: Settings schema 
'org.gnome.nm-applet.eap' is not installed

Seems related to https://issues.guix.gnu.org/41651 from two years ago.
