I've had a similar problem (see attached screenshot). In my case the size in bytes that it quotes is '/home' which is obviously nonsensical. In my case when I continue my installation it fails (see bug #205359), though I had that problem in beta but did not have the partition size problem in the beta, so they may be unrelated.
