Good point. I've found Tomas Janousek's diff and merged it into my 
xmonad.hs config:

-- Whenever a new dock appears, refresh the layout immediately to avoid the
-- new dock.
docksEventHook :: Event -> X All
docksEventHook (MapNotifyEvent {ev_window = w}) = do
     whenX ((not `fmap` (isClient w)) <&&> runQuery checkDock w) refresh
     return (All True)
docksEventHook _ = return (All True)

-- custom xmonad config
myConfig = defaultConfig
     {
     ...
     -- custom event hook to refresh layout if new dock does appear
     , handleEventHook       = docksEventHook
     ...
     }


Now it does work flawlessly, issue is gone.
I still find it rather as a hack than a bugfix but better then nothing :-)

Haskell is sweet ...


Take care
