Documentation for "Rietveld with Energies"

Hello,

Are there any tutorials or documentation on using the Rietveld with Energies or Pareto Optimization components within the Reflex module? While I can successfully use the Pawley and Rietveld components as well as normal FF optimizations, any attempts of using the Rietveld with Energy components just leads to the job crashing after 0 seconds without giving any useful debugging information.
