yes, the latest (shipshape) rockpool broke Epiphany... @gadgetoid fixed it in the master repo but I don't think it has made it's way into 'pre' yet as there are a couple of other bugs being worked on.
... you can grab it from https://github.com/pimoroni/flotilla-rockpool/tree/shipshape in the meantime (just overwrite the rockpool folder in your 'pre' git clone)
