Additional CSS sheets didn't work

Hi,
First of all, thanks for this incredible theme.

Backing to the issue...
I had some trouble wile adding an additional css. It just didn't work.

I fix this issue editing the file template.php:

Original code:

 // are there additional stylesheets
   $css_sheets = theme_get_setting('css_sheets');
   if ($css_sheets) {
      $css_sheets = explode("\n", $css_sheets);
      foreach ($css_sheets as $sheet) {
       drupal_add_css($basepath.$themepath.'/'.$sheet, 'theme');
      }
    $vars['styles'] = drupal_get_css();
   }

New Code:

   // are there additional stylesheets
   $css_sheets = theme_get_setting('css_sheets');
   if ($css_sheets) {
      $css_sheets = explode("\n", $css_sheets);
      foreach ($css_sheets as $sheet) {
       <strong>   drupal_add_css($themepath.'/'.$sheet, 'theme');</strong> // Changed this line
      }
    $vars['styles'] = drupal_get_css();
   }

Now its working, but it is in an Local drupal installation, maybe with the correct apache and php config the original code could work.

Thanks
