This bug is NOT fixed. I have exactly the same problem. I am using the latest ISO of regular ubuntu (not Xubuntu).
My hardware is quite different, the only thing I have in common with the above reporter is that I also have an "advanced partitioning" scheme (i.e. I set it up manually, since I like to have separate /boot, /home and / partitions, and I don't want ubuntu to delete my windows partitions and my backup partitions).
