I reverted the workaround in hash.c and fixed process_xml.c to process the EXTRA_ELEMENT tag correctly. The problem was the fact that the EXTRA_ELEMENT data should only be processing this tag if gmetad is in authority mode. It was missing a simple check for authority mode that the other tags included. Everything should be good now with gmetad and once the backport has been reviewed, we can included it in the next 3.1.1 release.
