ubiquity crashed with IndexError in render_slider()

Binary package hint: ubiquity

Xubuntu 9.10 alpha 3. During install process, after partitioner started I chose manual partition option. Crash flagged when I clicked 'forward' and 'scanning discs' notice appeared. The process seemed to continue without any adverse effects though.
