I have restful_authentication in use on an app and it has been working
fine, but I recently was changing the account creation flow and needed
to enable the UserObserver. I did so by including it in the
environment.rb (config.active_record.observers = :user_observer) and
Rails wouldn't start.
I got the following error;
source/communitysites/vendor/rails/activerecord/lib/active_record/

I get the same error when all the contents of UserObserver are
commented out, but don't get it if I load a different arbitrarily
named observer class. Adding some more debug statements to the Rails
dependencies code provided me this information;

After which I get the error. I am not very familiar with the Rails
internals since I am fairly new to the platform as well as the Ruby
language. Any tips on approaches for troubleshooting this (apparent
dependencies issue) would be greatly appreciated.
