    fix occassional crash caused by needlessly delayed signals (bko#363224)

    As pointed out by the Valgrind trace in #363224, delaying the signal causes
    the EffectWindow* argument to become invalid before the connected slot is
    called (this is because Qt discards only delayed signal->slot calls where
    the receiver gets deleted meanwhile, not the sender and definitely not
    a random argument.
    If the supposed glitches really happen, they should get fixed correctly,
    and for all cases (I doubt only desktop number would be involved but
    not e.g. shaded or minimized states).
