Nope, I wasn't on Saucy when this topic started lol when I changed the sources list it upgraded me to it for some odd reason (I picked 13.04, I must have misclicked). Anyways, I solved it (by reformatting lol) so there it is.
I believe Saucy is still in tha Alpha stages -- which means you're going to get breakage on a regular basis. You should really not use the pre-release versions unless you're an expert and easily able to deal with bugs. Also, when using a pre-release version, you should post in the Development section, not here.
Ubuntu 14.04, Mint 17; MS Win 8.1.
Will not respond to PM requests for support -- use the forums.
Saucy's gparted is 0.16.1, so it handles F2FS if that's something anyone wants to play with.
