    utils: be more robust against missing icons in gnome-icon-theme-symbolic
    
    When an icon is not found, we currently segfault, since we try to load a
    NULL GtkIconInfo. Avoid that, and at the same time use
    g_themed_icon_new_with_default_fallbacks() to possibly get a fallback
    icon in case the symbolic one is not found.
