[Jaunty] partitioner doesn't fit on screen with large number of partitions

Binary package hint: ubiquity

When installing Jaunty beta on a machine with a large number of partitions, the graphic representation at the top of the screen extends past the right edge of the screen, which apparently causes some of the buttons to be offscreen at the bottom right. There is no way to complete partitioning; the buttons to proceed are not visible and even keyboard shortcuts can't be used because there is no way to tell what keys to use.

I recommend this be triaged as critical, as there is no way to complete installation using the graphic installer on a machine with many partitions.
