I think I have found a bug in the Raspberry Pi services-admin application.
I have just undertaken a dist-upgrade to jessie.
If I run services admin I get the following
services-admin ** (services-admin:1645): WARNING **: Couldn't connect to accessibility bus: Failed to connect to socket /tmp/dbus-7NFArOJtg8: Connection refused Gtk-Message: GtkDialog mapped without a transient parent. This is discouraged.
However the window displays.
Which clearly doesn’t look right as I suspect the list of services should take up the whole window.
