You're passing the wrong argument to GEvent.removeListener().
GEvent.addListener() returns a listener object. That's what you need to save
in your arrays and later pass to GEvent.removeListener().
For example, instead of the two .push() calls you make after adding the two
listeners, you could push the correct values like this:
StartListeners.push( GEvent.addListener(
ZoneStartFinishMarkers[idStart], "dragend", function(){
...
} ) );
FinishListeners.push( GEvent.addListener(
ZoneStartFinishMarkers[idFinish], "dragend", function() {
...
} ) );
and change this part of your removal loop:
var pointerS = StartListeners[i];
var pointerF = FinishListeners[i];
GEvent.removeListener(StartFinishMarkers[pointerS]);
GEvent.removeListener(StartFinishMarkers[pointerF]);
to:
GEvent.removeListener( StartListeners[i] );
GEvent.removeListener( FinishListeners[i] );
