Ubiquity crashed on PowerPC after working a long time to install Lubuntu.

[Jeff Day]

Description: Ubuntu precise (development branch)
Release: 12.04

ubiquity:
  Installed: 2.9.23
  Candidate: 2.9.23
  Version table:
 *** 2.9.23 0
        500 http://ports.ubuntu.com/ubuntu-ports/ precise/main powerpc Packages
        100 /var/lib/dpkg/status

I expected the installation to complete and the bootloader to get installed.
We did the "Something Else" option, kept the existing sda1 new world boot partition, created a 2048m swap partition as sda2 and the rest of the drive as sda3 ext4 mountpoint /
The color theme looked a bit dark and hard to read but this is a Beta so that might be normal.

Things looked like they were going fine for about a half hour then we got a message that the installer crashed.
