Pb add break and tab space after submit or text/source buttu

Hi,

(sorry, french and my english is... very bad)

Ok, so,

I want use CKEditor, but i have a problem with p, blockquote tag ...

In my CKEditor box, i put a paragraph.

If i see "source", CKEditor add after p tag a break and a tabspace.
If i delete it, CKEditor add after p tag a break and a tabspace when i submit.

My config.js file is :

CKEDITOR.editorConfig = function( config )
{
   // Define changes to default configuration here. For example:
   config.language = 'fr';
   // config.uiColor = '#AADC6E';

   // Config personnalisée

   config.entities = false;
   config.entities_latin = false;

   config.on = {
   ev.editor.dataProcessor.writer.lineBreakChars = '';
        ev.editor.dataProcessor.writer.setRules( 'p',
                    {
                        indent : false,
                        breakBeforeOpen : false,
                        breakAfterOpen : false,
                        breakBeforeClose : false,
                        breakAfterClose : false
                    })
       };
};

Thx
