This may be the browser-dependency issue with recognition of accept
headers. I adapted a snippet that you can put in your
ApplicationController:
protected
def correct_safari_and_ie_accept_headers
ajax_request_types = ['text/javascript', 'application/json',
'text/xml']
request.accepts.sort!{ |x, y| ajax_request_types.include?
(y.to_s) ? 1 : -1 } if request.xhr?
end
What it does is sort the content types the browser claims to accept so
that the ajax'ey ones are first. That seems to fix a lot of this sort
of problem.

Hope this helps with your problem.
