Comment 2 for bug 298509

Same crash here with Ubuntu 9.04 Live CD install.

How to reproduce (at least on my system):
start livecd and either select to install a new system or to run a live cd.
If the latter, then start ubiquity manually by clicking the "install" shortcut on the desktop.

Set language, keyboard, time zone, ... and don't select any OS'es when offered to migrate settings from other OS'es on you system.
At the end click finish to start the installation.
The installation will start formatting/copying files/... and finally crash with the error mentioned above.
Result: an unusable, unbootable Ubuntu installation !

Apparently the problem has to do with the migration of settings form other OS'es.
While I selected to not migrate any settings, it appears that it is still trying to do so during installation.

How do I know ?
Because when you start ubiquity from a terminal window on the live cd with the following options:

    ubiquity --no-migration-assistant

The installation finishes without any errors.

Actually I don't know why I still choose to download the live cd, as it has never worked for me.
Each time a new Ubuntu version is released and I try to install through the live cd, something doesn't work and
in the end I always have to download the alternate install cd.
This time I was rather *lucky* that I found a workaround.

It's really incomprehensible that Ubuntu releases such crappy installation cd's
