Ubiquity not auto-restarting with "ubiquity ubiquity/reboot boolean true" in preseed file

Binary package hint: ubiquity

Ubiquity is supposed to forgo the reboot prompt when "ubiquity ubiquity/reboot boolean true" is listed in the preseed file. This is not happening. The cause is because the new ubiquity/poweroff tag was added. If I also include "ubiquity ubiquity/poweroff boolean false" in my preseed file, then my automatic install will reboot.

This is a regression from 10.10 and can be seen on the latest Ubuntu 11.04 Alpha 3 release
