@skoruppa It looks like the window doesn't have any class instance name - which sounds strange. Do you know how to code? Perhaps you could add a try-except clause around line 43 and output the window_group and window_name?

I think it is not nautilus fault. For me this looks like Spotify, just after run for like a one second, doesn't have any class name. Anyway, I have done as you said. Output without spotify

a version first. Use gi.require_version('Gtk', '3.0') before import to ensure that the right version gets loaded.
