I also experience this bug, on a Benq Joybook R55.
Unchecking use_time_for_policy did *not* fix this for me. Raising the time thresholds and checking use_time_for_policy did not either.
I guess confirming the upstream bug ( http://bugzilla.gnome.org/show_bug.cgi?id=506305 ) would help, if someone here has a gnome bugzilla account.
