The reason it worked for me is that I tried raid6 and you tried raid5. To make it work with raid5 you need the following patch. I haven't actually tested it as my test machine has had odd hardware issues for ages (only causing problems at reboot, but for a test machine, that is often..) and it is finally being looked at. Let me know if this gets you further.
