Ubiquity partitioner warns of resize when no resize requested

[Cefn]

Installing the Ubuntu Gnome Saucy Alpha 1. I found that after choosing the existing ext4 partition for '/' (without choosing to resize or format the drive), the partitioner warns something like 'changing the size of partitions means the partitioner changes need writing to disk'. This is despite the fact that no change in partition size has been requested.

A workaround is to avoid clicking the 'Continue' button (I was scared to think what would happen) but click the other button (possibly 'Return'). Then it succeeds in assigning the mount point anyway and you can proceed.
