Since nobody give me responce here, I do a manual fix on the code and now it’s working great.
Here is the fix:

In file /plugins/Dashboard/API.php on line 131 replace the function


    private function widgetExists($widget)
    {
        if (empty($widget->parameters)) {
            return false;
        }

        $module = $widget->parameters->module;
        $action = $widget->parameters->action;

        return WidgetsList::isDefined($module, $action);
    }

with this one


    private function widgetExists($widget)
    {
        if (empty($widget->parameters)) {
            return false;
        }
        elseif (!property_exists($widget->parameters, 'module')) {
	    return false;
	}

        $module = $widget->parameters->module;
        $action = $widget->parameters->action;

        return WidgetsList::isDefined($module, $action);
    }

and that will do the trick.
