issue when loading customConfig

HI,

I'm working with CKEditor and I'd like to create a custom config for it. i did this :

CKEDITOR.editorConfig = function( config )
{
   config.toolbar = 'toolbarLight';   

   config.extraPlugins = "timestamp,abbr,lien,model,unlnk,cng,img";
   config.removePlugins= "link";
  
   config.toolbar_toolbarLight =
   [
        ['Cut','Copy','Paste','PasteText','PasteFromWord'],
        ['Undo','Redo','-','Find','Replace','-','SelectAll','RemoveFormat'],
        ['Image','Table','HorizontalRule','SpecialChar'] ,
        '/',
        ['Source','Bold','Italic','Underline','NumberedList','BulletedList','Outdent', 'TextColor']
        ['Timestamp','Lien','Model','Unlnk','Img' ]
   ];
   
};

and I call the config like this :

<textarea id = "contenu_actualite" name="contenu_actualite" cols="200" rows="6" >&lt;p&gt;Initial value.&lt;/p&gt;</textarea>
						
<script type="text/javascript">

CKEDITOR.replace( 'contenu_actualite', { customConfig  : '../ckeditor1/js/ckeditor_config.js' } );
 
</script>

but this doesn't work for me i got this error from firebug :

TypeError: d is undefined
[Stopper sur une erreur] 	

...f:f.name,!b||-1==CKEDITOR.tools.indexOf(b,f))(f=a.ui.create(f))&&a.addFeature(f)...

ckeditor.js (ligne 631)

The probleme seems to be when i add my extra plugin since the thing work when i don't import them.

Any idea ?
