Hi all, I have fired up an cloud instance of Galaxy, 2 persistent nodes, scalable up to 10. I have updated the code to the latest stable, after issues with not being able to select multiple input for workflows (more background: http://dev.list.galaxyproject.org/selecting-multiple-inputs-for-workflows-no...) Running a workflow on multiple inputs (#=58) gives me - after a very long page loading - this error: ************************************************ Internal Server Error Galaxy was unable to sucessfully complete your request URL: http://ec2-54-226-11-122.compute-1.amazonaws.com/workflow/run?id=e967e0737bb...
