From https://www.openmicroscopy.org/qa2/qa/feedback/33803/
"I tried to create a new "Data Set" (by clicking the green folder icon in Omero.Web,under the "Explore" tab)
in an other members (an "All Members"-Project, icon is a grey-blue folder): Entered Name and Description (pruely ASCII-Letters of the latin alphabet, nothing fancy :), clicked "OK" and landed here: "Server Error. (500)".
