I have been using GlassMapper for a long time, and this piece of code has always worked flawlessly; today, after playing with the children of the Home item it no longer works - even if I undo my changes.

On Internet I found no documentation for this method and its failed states - under which circumstances I should be unable to retrieve the wrapper of the website root item?

The line in question is:

```cs
var root = new SitecoreContext().GetHomeItem<MenuPage>();

```
