custom error pages-- which exceptions to catch?

Hi all,

I implemented custom 404 and 500 error pages using rescue_from according to an example I found at http://blog.ubrio.us/code/rails-22-custom-error-pages-with-exception-loggable/

Here's my version:

  unless ActionController::Base.consider_all_requests_local     rescue_from ActiveRecord::RecordNotFound, ActionController::RoutingError, ActionController::UnknownController, ActionController::UnknownAction, :with => :render_404     rescue_from RuntimeError, :with => :render_500   end

  def render_500     render :template => "errors/error_500", :layout => 'singlecolumn', :status => 500   end

  def render_404     respond_to do |type|       type.html { render :template => "errors/error_404", :layout => 'singlecolumn', :status => 404 }       type.all { render :nothing => true, :status => 404 }     end     true # so we can do "render_404 and return"   end

Then I went to test it, by sticking a call to the undefined name "foobar" at the top of my homepage action. This raised a NameError, which wasn't caught by my 500 error catcher. Now, I can just add the error to the list, but I'm curious about other exceptions that could be raised that I haven't anticipated. When implementing custom error pages, which exceptions do folks like to catch?
