9.04-pre_release ubiquity crashed when selecting manual partitioning

[Ulisses Penna]

Binary package hint: ubiquity

When installing Ubuntu 9.04, pre release, and choosing Manual partitioning (step 5 of 8), ubiquity does not show any option in the "Use as" and "Mount point" fields and do not respond anymore and open up a bug report (the one I am sending).
