rspec users - Jun 2009 - [Cucumber] Successive requests with xml Content-Type fail?

I''m writing a cucumber test for an xml webservice.  When making
POST''s
the Content-Type in the header is set to "application/xml" and for any
request, the Accept header is set to "application/xml" (aka
Mime::XML.to_s)

I''m running into the following issue:

When I make two successive requests, the first one being a POST to log
the user in; the second one a GET to retrieve some data, the second
request always seems to fail with this error:

      private method `split'' called for
#<Mime::Type:0x7f60a708ff70>
(NoMethodError)
     
/usr/lib/ruby/gems/1.8/gems/actionpack-2.3.2/lib/action_controller/mime_type.rb:206:in
`method_missing''
      /usr/lib/ruby/gems/1.8/gems/rack-1.0.0/lib/rack/request.rb:51:in
`media_type''
      /usr/lib/ruby/gems/1.8/gems/rack-1.0.0/lib/rack/request.rb:117:in
`parseable_data?''
      /usr/lib/ruby/gems/1.8/gems/rack-1.0.0/lib/rack/request.rb:138:in
`POST''
     
/usr/lib/ruby/gems/1.8/gems/actionpack-2.3.2/lib/action_controller/request.rb:428:in
`request_parameters''
     
/usr/lib/ruby/gems/1.8/gems/actionpack-2.3.2/lib/action_controller/request.rb:381:in
`parameters''


This started happening only in Rails 2.3.  It previously worked fine
with Rails 2.0

Now, I dug into this some more; the Session class in webrat core seems
to get instantiated once for the entire scenario and the instance sticks
around for all of the requests.  I noticed by checking with the
debugger, that the header object gets transformed into a Rack header
object and acquires things like the referrer field from the first
request.  On the second request (the GET), the Content-Type is set but
it probably shouldn''t--as there is no payload data, it''s a
GET--and that
causes havoc.  I''m kind of lost as to whether this is a bug in Rack or
Rails or Webrat or whether I''m doing something wrong.

Any advice is appreciated.

Cucumber has had a separate list for some time now. Please post this
to http://groups.google.com/group/cukes.
