>Description:
bsdinstall segfaults in the autopart step when no disks are present.
>How-To-Repeat:
1. Download FreeBSD-9.1-RELEASE-amd64-dvd1.iso
2. Boot the iso (I used qemu-kvm) without any disks attached.
3. Give default/dummy answers until disk partitioning.
4. Select guided partitioning.

bsdinstall says an installation step has been aborted. On the third terminal you see:
Running installation step: autopart
Segmentation fault
Running installation step: umount

Expected results would be a nice message that automatic partitioning is not possible and that you should use manual partitioning or attach some disks.
