Bug Description

Ubiquity crashes if I uncheck format option from "Something Else" advanced install option.

Steps to reproduce:

1. I created in Gparted:
    Partition Table in MBR (msdos), NON-EFI system
    /dev/sda1 -- 1024 MiB EXT4
    /dev/sda2 -- 30 GiB Btrfs
    /dev/sda3 -- 205 GiB Btrfs
    /dev/sda4 -- 4 GiB linux-swap
2. Opens Ubiquity for install (or try "Install session" from the start)
3. Select "Something Else" in Installation Type
4. Double click in sda2 partition, Use as: "Ext4 journaling file system", Mount Partition: /, and click OK (DO NOT select for format it)
5. Partition will be marked to formatting, so double click it again, and change to "btrfs journaling file system", check Format option (it will be already checked) and click OK
6. Partition will not be checked to formatting, so check format columm
7. Ubiquity will crash

If you try it in "Install session", then an apport pop-up appears, you click in Continue and you will go to a black screen, it's possible to see only mouse icon.

Ctrl+Alt+F1 to tty1, and you will see tty1 display and mouse icon (you can move it, strange behavior).

There are no effective report to launchpad, both in "Install session" and desktop session.
