Description
Created attachment 314303 gnome-mouse-properties.ui
When loading the attached .ui file, I can see the UI, but none of the widgets show up in the widget tree, and clicking on any widget throws: (glade:21735): GladeUI-CRITICAL **: glade_project_selection_set: assertion 'glade_project_has_object (project, object)' failed
