Ошибка импорта виджета Orchard Html

Question

После импорта содержимого виджета html с помощью cms "вкладка импорта" возникает следующая ошибка: (Orchard 1.8.0) (ошибка возникает только при выборе левого пункта меню "виджеты" на панели инструментов)

Похоже на http://orchard.codeplex.com/workitem/17992 но решение не в Orchard 1.8 все же оно появляется?
