QA 4.2 : KDE services persist when cancelled

[purslow at sympatico.ca]

following the discussion earlier today, i thought i would compare
KDE & Xfce start-up times without any applications & KDE services in Xfce.
i closed everything which was running on desktops in both environments
& in Xfce 4.2 unchecked the box to start KDE services in the settings manager.
when i rebooted & restarted Xfce, KDE services started regardless,
as shown by Pstree in an Xterm & by instant opening of a Konsole afterwards:

     |-kdeinit---kdeinit
     |-2*[kdeinit]
     |-keventd
     |-khubd
     |-kio_uiserver
     |-klogd
     |-7*[konqueror]
     |-kreiserfsd
     |-kscand
     |-ksoftirqd_CPU0
     |-kswapd
     |-kupdated
 
 ~/.config/xfce4-session/xfce4-session.rc  still contains

  LaunchKDE=false

it looks as if when KDE services are unchecked in the settings manager,
no note is made for use by the session manager not to restart them
as part of the otherwise empty new session.

the work-around would be to kill all the above processes before logout,
but it does look like a small oversight in the session-manager's behaviour,
which perhaps deserves to be fixed before 4.2-final.

i believe someone else may have mentioned this under another thread.
