I'm a little confused be what you mean when you say "exception_response".
Have you considered using Exception Views
http://pyramid-cookbook.readthedocs.org/en/latest/pylons/exceptions.html#exception-views?
The primary difference would be that you would want to return a 200 status
code instead of 500 so that jQuery will appropriately handle your response
like you want.
