Fatal error when Page manager enabled and used

Probably related to this, when trying to edit CTools example plugin get:

Notice: Array to string conversion in page_manager_render_operations() (line 1211 of D:\xxx\sites\all\modules\ctools\page_manager\page_manager.admin.inc).

Thanks for your response.

I cannot complete website design without this being addressed, please help.

The dev release states it is not functional yet.

Some additional information - clickon on CTools example throughs the same failure:

Fatal error: Unsupported operand types in D:\xxx\includes\theme.inc on line 989

Pumin is correct, clicking on the Ctools plugin example cause the same error as clicking on structure/pages.

I applied this patch and problem still occurs.

Here is code snippet line 957-995

  $info = $hooks[$hook];
  global $theme_path;
  $temp = $theme_path;
  // point path_to_theme() to the currently used theme path:
  $theme_path = $info['theme path'];

  // Include a file if the theme function or variable processor is held elsewhere.
  if (!empty($info['includes'])) {
    foreach ($info['includes'] as $include_file) {
      include_once DRUPAL_ROOT . '/' . $include_file;
    }
  }

  // If a renderable array is passed as $variables, then set $variables to
  // the arguments expected by the theme function.
  if (isset($variables['#theme']) || isset($variables['#theme_wrappers'])) {
    $element = $variables;
    $variables = array();
    if (isset($info['variables'])) {
      foreach (array_keys($info['variables']) as $name) {
        if (isset($element["#$name"])) {
          $variables[$name] = $element["#$name"];
        }
      }
    }
    else {
      $variables[$info['render element']] = $element;
    }
  }

  // Merge in argument defaults.
  if (!empty($info['variables'])) {
    $variables += $info['variables'];    <<<<--------- line 989
  }
  elseif (!empty($info['render element'])) {
    $variables += array($info['render element'] => array());
  }

 

Disabling Ctools plugin solved the problem, thanks.
