kind_N field throws error when used

[BristleBeard]

When using kind_N as a field, I get the below error:

    raise Fault(**self._stack[0])
xmlrpc.client.Fault: <Fault -503: 'Command "kind_95" does not exist.'>

During handling of the above exception, another exception occurred:

I'm able to reproduce these results using this command: rtcontrol is_complete=yes -o custom_1,name,realpath,kind_95,hash,directory
