Found this in compression.rb, not sure what else to look at without actually having the compressed chunk. When Puppet encounters such a failure, it tends to repeat, for what it's worth:

In some local testing an 'incorrect header check' is thrown by Zlib::Inflater#inflate passed invalid data.

                                                          def uncompress(chunk)
        out = @uncompressor.inflate(chunk)
        @first = false
        return out
      rescue Zlib::DataError
        # it can happen that we receive a raw deflate stream
        # which might make our inflate throw a data error.
        # in this case, we try with a verbatim (no header)
        # deflater.
        @uncompressor = Zlib::Inflate.new
        if @first then
          @first = false
          retry
        end
        raise
      end

I haven't found anything out there so far, so I thought I'd just document it while I'm at it.

We ran into some other problem with the changes in net/http Ruby 2.1.0 introduced around the handling of gzip/deflate encoded content. This MIGHT be related.
So far we haven't been able to fix it.
