Theme Style.css Error

Hello,

I am Testing TinyMCE on a site including these modules :
adminblock, advanced_menu, authorship, comment, contact, forum, help, locale, menu, page, poll, profile, statistics, taxonomy, and upload.

After instaling TinyMCE, I started to get the following error (3 times) in the administer/settings menu.

# warning: file_exists() [function.file-exists]: open_basedir restriction in effect. File(/style.css) is not within the allowed path(s): (F:/Web Site/resonance/philippot-huang.com) in F:\Web Site\Resonance\philippot-huang.com\modules\tinymce\tinymce.module on line 604.

After a full debug with backtrace

I noticed that the global variable $theme is erased during the

    require_once './includes/bootstrap.inc';
    drupal_bootstrap(DRUPAL_BOOTSTRAP_FULL);

part of index.php.

To Get it work I updated the theme.inc file as follow :

function path_to_theme() {
  global $theme;

  // Added to allow initialization  if not set.
  if (!isset($theme)) {
    init_theme();
  }

  $themes = list_themes();
  return dirname($themes[$theme]->filename);
}

I am new to drupal and I am not sure it was the good solution but it work.

If there is an official patch please let me know

Thanks
