ShowExceptions serves text/html even to XHR requests that don't accept it

Reported by John Firebaugh | October 29th, 2010 @ 11:51 PM

The ActionDispatch::ShowExceptions middleware renders an HTML template without checking whether it's responding to XHR and the client accepts text/html.

Instead it should follow logic similar to Rack::ShowExceptions, which serves text/plain if:

  env["HTTP_X_REQUESTED_WITH"] == "XMLHttpRequest" && (!env["HTTP_ACCEPT"] || !env["HTTP_ACCEPT"].include?("text/html"))

The question is, what should the body contain in that case? Something like this?
