ActiveResource: Disallowed type attribute: "symbol" in Rails 3.2.11

Has anyone started seeing the error:

Disallowed type attribute: "symbol"

when making an ActiveResource call after upgrading to Rails 3.2.11?

I found this blog entry which seems to completely describe the problem:
http://techtime.getharvest.com/blog/activeresource-xml-bug-fix-for-rails-3-dot-0-19but
it claims that the problem was only in older versions of Rails.

There is a proposed fix for Rails 3.0, but that obviously wouldn''t help
me.

I was wondering if the problem was in all versions of Rails, not just 3.0.
It did just appear and neither my web service nor the ActiveResource model
has changed recently.
