New flash error (to me at least)

programming flash
1

256 levels of recursion were exceeded in one action list.
This is probably an infinite loop.
Further execution of actions has been disabled in this movie.

I just got this is the console window in a flash movie, i am curren;t coding an uploader that submits some info to MySQL when it is finished, never seen this before. Any ideas would be appreciated.

function uploader() {
    leftbar.uploader.ok._visible = true;
    var file_fr:FileReference = new FileReference();
    var list_obj:Object = new Object();
    list_obj.onSelect = function() {
        file_fr.upload(_global.url+"upload.php");
        leftbar.uploader.descriptioninput.text = file_fr.name;
        _global.filename = fileRef.name
    };
    list_obj.onComplete = function(fileRef) {
        
        leftbar.uploader.descriptioninput.text = "Adding to Database";
        var addImage:LoadVars = new LoadVars();
        addImage.action = addImage;
        addImage.nametext = leftbar.uploader.nameinput.text;
        addImage.descriptiontext = _global.uploaddescription;
        addImage.path = _global.filename
        addImage.sendAndLoad(_global.url+"list.php?ck="+randRange(0, 1000), addImage, "POST");
        addImage.onLoad = function() {
            leftbar.backbutton.onPress();
            loadimages("last");
            leftbar.uploader.descriptioninput.text = "All Done";
            rec_mc.clear();
            leftbar.uploader.ok.enabled = true;
        };
    };
    list_obj.onProgress = function(file:FileReference, bytesLoaded:Number, bytesTotal:Number):Void  {
        var percent = Math.floor(bytesLoaded/bytesTotal*100);
        leftbar.uploader.descriptioninput.text = percent+"% Uploaded";
    };
    list_obj.onCancel = function() {
        leftbar.uploader.descriptioninput.text = "Cancel was selected";
    };
    list_obj.onIOError = function(fileRef) {
        leftbar.uploader.descriptioninput.text = "IO error with "+fileRef.name;
        
    };
    list_obj.onSecurityError = function(fileRef, error) {
        leftbar.uploader.descriptioninput.text = "Security error with "+fileRef.name+":"+error;
    };
    list_obj.onHTTPError = function(fileRef:FileReference, error:Number) {
        leftbar.uploader.descriptioninput.text += "HTTP error: with "+fileRef.name+":error #"+error;
    };
    file_fr.addListener(list_obj);
    leftbar.uploader.ok.onPress = function() {
        _global.uploaddescription = leftbar.uploader.descriptioninput.text;
        leftbar.uploader.ok.enabled = false;
        file_fr.browse([{description:"Images", extension:"*.JPG;*.jpg,*.GIF,*.gif,*.PNG,*.png"}]);
    };
}
