CKeditor + Geshi, requires styles

Hi. S.orry for my english.

Używam pluginu Geshi do kolorowania składni. So far I have used CKEditor 3.x, I wanted to go to a newer version. I've encountered a problem when adapting the code. My current code:

CKEDITOR.plugins.add( 'geshi',
{
  requires : [ 'styles', 'button' ],

  init : function( editor )
  {
    // All buttons use the same code to register. So, to avoid
    // duplications, let's use this tool function.
    var addButtonCommand = function( buttonName, buttonLabel, commandName, styleDefiniton )
    {
      var style = new CKEDITOR.style( styleDefiniton );
 
      editor.attachStyleStateChange( style, function( state )
      {
        editor.getCommand( commandName ).setState( state );
      });
 
      editor.addCommand( commandName, new CKEDITOR.styleCommand( style ) );
 
      editor.ui.addButton( buttonName,
      {

        label : buttonLabel,
        command : commandName

      });
    };

    var config = editor.config;
//    var lang = editor.lang;
 
    addButtonCommand( 'Geshi-code'  , 'code'   , 'Geshi-code'        , config.coreStyles_code );
    addButtonCommand( 'Geshi-php'    , 'php'     , 'Geshi-php'        , config.coreStyles_php );
    addButtonCommand( 'Geshi-mysql'  , 'mysql'   , 'Geshi-mysql'      , config.coreStyles_mysql );
    addButtonCommand( 'Geshi-html'  , 'html'   , 'Geshi-html'        , config.coreStyles_html );
    addButtonCommand( 'Geshi-xml'    , 'xml'     , 'Geshi-xml'        , config.coreStyles_xml );
    addButtonCommand( 'Geshi-css'    , 'css'     , 'Geshi-css'        , config.coreStyles_css );
    addButtonCommand( 'Geshi-js'    , 'js'     , 'Geshi-js'          , config.coreStyles_js );
    addButtonCommand( 'Geshi-jquery', 'jquery' , 'Geshi-jquery'      , config.coreStyles_jquery );
    addButtonCommand( 'Geshi-smarty', 'smarty' , 'Geshi-smarty'      , config.coreStyles_smarty );
    addButtonCommand( 'Geshi-text'  , 'text'   , 'Geshi-text'        , config.coreStyles_text );
  }
});

//CKEDITOR.buttonLabel_code = {'code'};
// Basic Inline Styles.
CKEDITOR.config.coreStyles_code      = { element : 'pre' };
CKEDITOR.config.coreStyles_php      = { element : 'pre', attributes : { 'lang' : 'php' } };
CKEDITOR.config.coreStyles_mysql    = { element : 'pre', attributes : { 'lang' : 'mysql' } };
CKEDITOR.config.coreStyles_html      = { element : 'pre', attributes : { 'lang' : 'html4strict' } };
CKEDITOR.config.coreStyles_xml      = { element : 'pre', attributes : { 'lang' : 'xml' } };
CKEDITOR.config.coreStyles_css      = { element : 'pre', attributes : { 'lang' : 'css' } };
CKEDITOR.config.coreStyles_js        = { element : 'pre', attributes : { 'lang' : 'Javascript' } };
CKEDITOR.config.coreStyles_jquery     = { element : 'pre', attributes : { 'lang' : 'jquery' } };
CKEDITOR.config.coreStyles_smarty     = { element : 'pre', attributes : { 'lang' : 'smarty' } };
CKEDITOR.config.coreStyles_text      = { element : 'pre', attributes : { 'lang' : 'text' } };

Problem with the line:

requires : [ 'styles', 'button' ],

So far, the plugin file fetch styles styles such as kama / editor.css. It crashes the code.
