I often noticed when logging out that my Evolution window changed appearance: it looks like the GTK theme changes before Evolution is closed. To me, this is symptomatic of gnome-settings-daemon dying, so I suspect it is stopped before Evolution, maybe because Evo is a slow app to stop (waiting for e-d-s stuff...).

The visual result is quite poor since you see your desktop changing appearance with no reason. But I guess this also has a performance impact, since changing the theme of all GTK app usually takes a few seconds; this does not make sense on logout.

So, is there a way to ensure g-s-d is only stopped at the end, when no other app is still alive?
