Activeresource-2.3.2 HTTPHeaderSyntaxError

Rails
1

Hi,

I’m upgrading my app from 2.2.2 to 2.3.2 and am having a problem with
ActiveResource.

class FooResource < ActiveResource::Base
  self.site = "whatever"
  self.element_name = "foo"
end

FooResource.create(:bar => 'baz')

raises:

Net::HTTPHeaderSyntaxError: wrong Content-Length format

I’m using ruby 1.8.7p160 on OSX, also tried different ruby versions.
This is working fine with rails 2.2.2. Has anyone dealt with this
problem before?

Thanks,
Christian

Turns out that Rails 2.3.2 (specifically Rack) is incompatible with
Mongrel 1.0.1. Updating to the latest Mongrel gem 1.1.5 solved the
problem.
