strace showed to me that nautilus calls gio which for some reason ends up calling exo-open from Xfce desktop which fails. This has possibly something to do with Gnome 3 running with wayland and Xfce runs under X11. execve("/usr/bin/gio", ["gio", "open", "video.mp4"], 0x7ffd8d0aff40 /* 45 var s */) = 0 ... openat(AT_FDCWD, "/usr/share/applications/exo-file-manager.desktop", O_RDONLY) = 8 ... ** (exo-helper-1:4657): WARNING **: Could not open X display Gtk-Message: GtkDialog mapped without a transient parent. This is discouraged. After removing exo-utils package nautilus can open files again with external applications. So 'apt-get remove exo-utils' is the best workaround thus far. Maybe exo-utils from Xfce is hijacking something from Gnome desktop... -Mikko
