Bug#840234: gnome-shell-extensions: Settings windows are all blank

[Bruno BEAUFILS]

Package: gnome-shell-extensions
Version: 3.22.0-1
Severity: normal

Dear Maintainer,

The settings window of any gnome-shell extensions (from
http://extensions.gnome.org or gnome-tweak-tool) stay blank (as seen in the
attached screenshot). It is thus impossible to change any settings from the
default ones.

The following error messages appears in console:

    (gnome-shell-extension-prefs:16197): Gjs-WARNING **: JS ERROR: Error: No
property propagate_natural_width on this GObject GtkScrolledWindow
_init/Gtk.Widget.prototype._init at resource:///org/gnome/gjs/modules/overrides/Gtk.js:107
Application<._buildUI at resource:///org/gnome/shell/extensionPrefs/main.js:156
    wrapper at resource:///org/gnome/gjs/modules/lang.js:178
Application<._onStartup at resource:///org/gnome/shell/extensionPrefs/main.js:222
    wrapper at resource:///org/gnome/gjs/modules/lang.js:178
    main at resource:///org/gnome/shell/extensionPrefs/main.js:377
    @<main>:1

Everything worked nicely in jessie. I do not know if it is broken since some
weeks in stretch or if it is due to something in my config.
