After recently upgrading to Drupal 6.24, I am now seeing this error on some pages.

Fatal error: Unsupported operand types in /var/www/d6/includes/common.inc on line 1624

Following the recommendations on http://drupal.org/node/362799, I now see the following. Any help understanding how jarousel is connected to the common.inc error is greatly appreciated.

array (
  'file' => '/var/www/d6/sites/all/modules/jcarousel/jcarousel.module',
  'line' => 151,
  'function' => 'url',
  'args' => 
  array (
    0 => 'jcarousel/ajax/views',
  ),
)

array (
  'file' => '/var/www/d6/includes/theme.inc',
  'line' => 1871,
  'function' => 'url',
  'args' => 
  array (
  ),
)

array (
  'file' => '/var/www/d6/includes/common.inc',
  'line' => 1649,
  'function' => 'url',
  'args' => 
  array (
    0 => '',
    1 => 
    array (
      'attributes' => 
      array (

      'html' => false,
    ),
  ),
)
