Comment 5 for bug 1739468

This code in gnome-shell-extension-appindicator-17.10.3 doesn't make sense, because the "reset" function doesn't do anything:

    _ensureItemRegistered: function(service, bus_name, obj_path) {
        let id = this._getItemId(bus_name, obj_path);

        if (this._items[id]) {
            //delete the old one and add the new indicator
            Util.Logger.warn("Attempting to re-register "+id+"; resetting instead");
            this._items[id].reset();
        }

        this._registerItem(service, bus_name, obj_path)
    },

The result is that _ensureItemRegistered outputs a warning and then _registerItem also outputs a warning (because it's already registered).

RegisterStatusNotifierItemAsync is being called twice every 10 seconds since gnome-shell started:

The indicator-multiload-0.4 update interval is set to 10 seconds. If I change this then it affects the frequency of the warnings.

It's registering twice every 10 seconds:

There is only one indicator-multiload process running.

The tray icon doesn't appear to be working properly (it's always square with coloured vertical bars):

Turning off all the graphs does not fix the registration warnings.
