Had the same problem, also waited for an update to solve it, but nothing changed. I checked the system directories, which are on the same partition but you have no right to look into them without root (pretty dumb if you ask me). I found a dir /data/gps filled with some useless txt files. Then after deleting them with Ghost Commander nearly 2 GB of free space reappeared.
Sorry it took me so long, not checking xda regularly lately.
