Bug: Cannot attach after failed loadClip

Question

Hi, this is sort of a bug report unless somebody in this forum can prove me wrong. I've stumbled several times across this problem in my project always scratching my head of this undesirable behavior until i finally decided to create a simpler script to reproduce the problem. Here it goes. If you attempt to load an image into a movie clip and the load fails, you are unable to attach a library movie clip to it. The code below is from the fla file i attached herewith. All you need is a movieclip in your library with linkage name "Attach_MC" and this script in a 1-frame fla file. Or just download the fla file. What i am trying to do is attach a movieclip with a graphic that says "loading failed" if the load fails, so that it won't be blank but i can't do it unless perhaps by a workaround by placing a reserve clip in the same place (i.e. under a mask).
import mx.utils.Delegate;
var mcGlobal:MovieClip = this.createEmptyMovieClip("Stage_MC", 0);
var cLoader:MovieClipLoader = new MovieClipLoader();
var oListener:Object = new Object();
oListener.onLoadInit = Delgate.create(this, onLoadSuccess);
oListener.onLoadError = Delegate.create(this, onErrLoad);
cLoader.addListener(oListener);
cLoader.loadClip("intentional_wrong_path", mcGlobal);
function onLoadSuccess(fSuccess:Boolean):Void {}
function onErrLoad(mcClip:MovieClip):Void
   trace("Clip: " + mcClip); //Exists = mcGlobal
   var mcNested:MovieClip = mcClip.createEmptyMovieClip("Empty_MC",0);
   trace("Empty_MC: " + mcNested); //Creating Empty MC works
   //But attaching does not work!!! Undefined!!
   var mcAtt1:MovieClip = mcNested.attachMovie("Attach_MC", "Att_MC", 10);
   var mcAtt2:MovieClip = mcClip.attachMovie("Attach_MC", "Att_MC", 10);
   trace("Att1_MC: " + mcAtt1);
   trace("Att2_MC: " + mcAtt2);
Any responses pertaining to this problem are highly appreciated.

you're welcome.
p.s.  there are work-arounds.  you can create parent and child movieclips and use the child for the load-target and the parent for the attachMovie target.  that will work whether there's a load failure or not.
