[DRE-maint] Bug#701629: ruby-json: After upgrade ruby-json from 1.7.3-2 to 1.7.3-3 chef-client stops working

[Bastian Neuburger]

Hi,


I experienced the same thing.

When first registering the client/node at the chef-server chef-client 
runs fine, but each chef run afterwards, it fails.

The reason is that the data structure sent by the chef-server to the 
node was parsed as an object of class Chef::Node with ruby-json 1.7.3-2 
and with 1.7.3-3 it is recognized as a hash instead of Chef::Node.
Therefore the NoMethodError is thrown, since the chef sources only 
implement a function reset_defaults_and_overrides for the Node class, 
not for the Hash class.

After downgrading the ruby-json package to 1.7.3-2 works, chef-client 
works again.

I'm not sure if this bug report should also be filed against the chef 
package with a higher severity, but since the Debian Ruby Extras 
Maintainer take care of both packages, maybe they can decide.

Cheers,

Bastian
