Does not work if 404 in root controller

[jackkinsella]

I tried calling an erroneous route http://www.example.com/j and instead of the exception notifier in line templates, I got the default rails red screen of death "The page you were looking for doesn't exist.

The notifier works fine on this app in the case of non root errors (e.g. users/j)

Here is my stack trace:
