Puppet users - Jul 2013 - Could not intern from yaml: undefined method `intern' for nil:NilClass

Hi everyone, 
I''m stuck with this error trying to set up inspection reports :
 
Could not send report: Error 400 on SERVER: Could not intern from yaml: 
undefined method `intern'' for nil:NilClass


Earlier, I had this one : 

Could not run: Could not find catalog for hostname

That I fixed with : catalog_cache_terminus = yaml 

Agent and server are running puppet 3.2.3.

Full trace here :
[root@hostname ~]# puppet inspect --trace

/usr/bin/puppet:4
Notice: Finished inspection in 0.59 seconds

I wasn''t able to find anything related to this on the web.
So I would really enjoy any hint on how to fix this.

Thanks.
