Rails: Error display for helpers shows only the originating line in the view

Question

If I have an error in a view's helper function, Rails will report the line from which the helper function was called. e.g. If I have in my view the line:

<%= bad_function %>

And in my helper file

def bad_function
  non_existant_call
end

Then Rails would point me to the former ERB file as the source of the error. Is there any way to improve error reporting for views and helpers?

I am using Rails 2.3.8.
