Comment 2 for bug 1481536

I've gotten this message as well for Kubuntu Wily, but I didn't have issues unlocking it. I first get the prompt screen for cryptsetup to enter password, I then enter correct password for it, I then get: "Unknown Fstype, bad password or options?" Then it gives message "sda5_crypt setup successfully", and then loads up the user /password prompt screen before entering into desktop / Kubuntu Wily. Not sure why I would get "Unknown fstype, bad password or options?" message, when I entered correct password from get go lol.
