I encountered the same error with the i386 08-27 daily build, but I had first booted into the Live Desktop and updated ubiquity to version 2.3.9.
In my case the crash notification popped up almost immediately after selecting "Specify partitions manually (advanced)". I had not even clicked on Install Now yet.
