I don't think any actual person was logged in, but gdm was running.  And
apparently gdm starts gsd-power, the gnome-settings power demon.  I
haven't yet been able to find where gsd-power gets its settings, but maybe
it's that, together with treating network activity as "activity" for the
purposes of deciding when to sleep.  Does anyone here know?

If it was gsd-power that was putting the machine to sleep, it wasn't
putting anything in the log saying that.
