User order history bug

[Lexiboy]

The menu item type 'list orders' links all user orders, but they cannot be viewed in detail. When you click on an order instead of the details you get this message "Order not found! It may have been deleted."

The link to an order looks something like this:
http://www.lemongrasshouse.ru/интернет-магазин/заказы/id/52/подробнее


Via account maintenance it all works fine, the link looks like this:
