[Bug 52368] crash while unable to setup partition for installation

[Jean-Pierre Riviere]

Public bug reported:

I have my IDE hard drive already set up for linux, with a swap
partition, two /boot partition (one for fedora, one which was intented
for ubuntu) and one for LVM, which has /home, two / and one /tmp. All
partitions are primary partition.

As I was trying to install ubuntu, I choosed the manual partitionning.
The system began scanning, with a ghosted image of a partition tool. But
the ghost disappeared, leaving me without any possibility to say where
to put what. I can't install ubuntu!

However the "continue" button was available. So I press it, and this
broke the installe (this is where it is different from bug 40542, and
also that until then the installer was not crashed yet).

Traceback (most recent call last):
  File "/usr/bin/ubiquity", line 130, in ?
    install(sys.argv[1])
  File "/usr/bin/ubiquity", line 55, in install
    ret = wizard.run()
