[chef] chef gem version mismatch?

[John Merrells < >]

I have a client that tries to authenticate with the server, but it gets back 
a 500 response.

`api_request'

This is what happens on the server side.

for nil:NilClass - (NoMethodError)

/usr/lib/ruby/gems/1.8/gems/chef-0.8.10/lib/chef/node.rb:328:in `json_create'

I do have a different version of the chef gem on the server and client, but I 
have lots of client machines with 0.9.0 and they seem to be just fine....

Any thoughts on what might be going on here?

John
