[rules-users] Serialization issue.

[Federico Bertola]

Dear all,
Some time ago I've submitted a pull request (#353) fixing a situation 
where a rule with large text prevent the serialization of the knowledge 
package.
This is now the only thing that prevent us form using the original 
distribution. If there's nothing wrong or risky in it, it is possible 
for you apply the fix so we can use the latest snapshot?

Thank you very much for your patience :)

Regards,
Federico.
