Public bug reported: When I did doble-click on top of a font the font viewer is not open.
When I run from the console the command `gnome-font-viewer in-mono.otf` it shows this error: ⇒ gnome-font-viewer in-mono.otf (gnome-font-viewer:3639): GLib-GObject-WARNING **: invalid (NULL) pointer instance (gnome-font-viewer:3639): GLib-GObject-CRITICAL **: g_signal_connect_data: assertion 'G_TYPE_CHECK_INSTANCE (instance)' failed (gnome-font-viewer:3639): Gtk-CRITICAL **: gtk_widget_get_scale_factor: assertion 'GTK_IS_WIDGET (widget)' failed [1] 3639 segmentation fault (core dumped) gnome-font-viewer in-mono.otf If I try with sudo throws this other error: ⇒ sudo gnome-font-viewer in-mono.otf No protocol specified Unable to init server: Could not connect: Connection refused (gnome-font-viewer:3609): Gtk-WARNING **: cannot open display: :0 I tried with different kind of fonts (ttf, otf ...)
