The problem appears to only be an issue on the latest versions on
conda-forge. Removing theconda-forgechannel from the environment worked for me.environment: remove conda-forge channel

I can confirm the regression is in versions>=0.3.0 of cloudpickle, version 0.2.2 from January of 2017 is fine. I'm going to land a commit backing off to 0.2.2 of cloudpickle, since dask currently seems to be happy with >= 0.2.1.
