Description of problem: (nemo:19359): Gtk-WARNING **: Failed to register client: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.gnome.SessionManager was not provided by any .service files Initializing nemo-image-converter extension The Message states correctly, that there is no servicefile for systemd which has the requested name in it. ( I assume systemd is meant ) Version-Release number of selected component (if applicable): 3.0.6 FC24 64bit How reproducible: start it in a bash by hand Additional Note: I may or may not, be a problem of this installation regarding dbus.
The warning is expected when running as sudo or root, running it as normal user doesn't produce it.

I have the same issue on F28, and I'm not starting anything in the bash by hand. My shutdown-dialog takes a long time (some 20 s) to open. I have plenty of these errors when I'm running dbus-monitor when opening the shutdown-dialog. See https://gitlab.gnome.org/GNOME/gnome-shell/issues/309
