I'm using Rails 2.3.5 with nzkoz/rails_xss plugin, but I've just
tested it with Rails 2.3.8 with rails/rails_xss and it's the same.

The error is caused by this line in the layout:
= facebook_sign_in_link :user

Here's the application trace:
undefined method `<<' for #<Haml::Helpers::ErrorReturn:
0x000001081a3c20>

I was trying to fix it with various concat/capture combinations, but
the only thing that I managed to get was this:
"form_for outputs directly to the Haml template. Disregard its return
value and use the - operator, or use capture_haml to get the value as
a String."
