exception_logger and protect_from_forgery

I am having a problem using the exception_logger plugin when I have
protect_from_forgery enabled.

Here is the line from application.rb:
protect_from_forgery :secret => 'xxxx'

But I am getting:
No :secret given to the #protect_from_forgery call. Set that or use a
session store capable of generating its own keys (Cookie Session
Store).

Now, if I remove the secret and try and use MY controllers I get that
error, but it goes away when the secret is there.

Any ideas what the issue is?
