ubiquity crashed with ImportError in <module>() [ubuntu 9.04 alpha]

[Zerp64]

Binary package hint: ubiquity

Using Ubuntu 9.04 daily build on Feb 23, 2009.

On VirtualBox 2.1.4 on Ubuntu 8.10 host. Latest updates.

Clicked on the 'Install' icon to install, but no window popped up. I saw 'starting administrative application' on the GNOME panel, but after that nothing.
