Bug#1082529: gnome-characters: application fails to start 'Gjs_MainWindow': .:0:0 Invalid object type 'AdwSpinner'

[SubOptimal]

Package: gnome-characters
Version: 47.0-1
Severity: important
X-Debbugs-Cc: frank.dietrich at gmx.li

Dear Maintainer,

starting the application from command line reveals the following error

--- start ---
Gjs-Message: 17:07:53.684: JS LOG: Characters Application started

(org.gnome.Characters:87626): Gtk-CRITICAL **: 17:07:53.701: Error building

run at resource:///org/gnome/gjs/modules/script/package.js:207:19

--- end -----

The application does not create a visible window, but keeps running in the
background.

cheers
Frank
