Net SCP error when using nodes

[rneu31]

Returning to a cookbook I wrote a few months ago... I now see this error:

       Removing non-cookbook files before transfer
       Preparing data_bags
       Preparing nodes
       Preparing validation.pem
       Preparing client.rb

Does this mean anything to anyone? If I use chef_zero provisioner this does not happen. I'm currently pretty stumped.

Just ran kitchen converge -l debug and the error did not occur, after numerous non-debug runs in a row failing. Today isn't even Monday.
