I have installed this on fedora 13 and the thumbnail display for album art is working fine. But i get following error when i run "cover-thumbnailer-gui". Not sure if there is any dependency is missing

/usr/bin/cover-thumbnailer-gui:277: GtkWarning: Ignoring the separator setting
win.add_from_file(os.path.join(BASE_PATH, "cover-thumbnailer-gui.glade"))
