Installer offers to install into new partition on -37% of the disk

[Peter McCurdy]

Binary package hint: ubiquity

Reproduction steps:

1. In a virtual machine, create a new 6 GB disk.
2. Partition the drive so it contains a 256 MiB fat32 partition on sda3, a 512 MiB swap partition on /dev/sda2, and the remainder (about 5400 MiB) as ext3 on /dev/sda1. All partitions were primary partitions. In my case, I had an older Ubuntu installation on /dev/sda1.
3. Reboot into the 8.10 beta live CD.
4. Start the installer, click Next until the partitioning screen shows up.
5. Observe the proposed guided partitioning scheme.

Expected: The partitioner proposes a hard drive arrangement that is physically possible.
Actual: "How do you want to partition the disk? Before (/dev/sda1=88%, /dev/sda2=7%, /dev/sda3=3%), After (/dev/sda1=88%, /dev/sda2=7%, /dev/sda3=41%, Ubuntu 8.10 -37%)"

The graphic showing the partition distribution is the same for both before and after.

Thanks for your report. This is also bug 271512, fixed post-beta.
