OpenGEU LiveCD Install Crashed @ 74%

Binary package hint: casper

Installing OpenGEU from LiveCD Instance running in VMWare workstation on Ubuntu Heron, got a "Installer crashed" dialog box with the following details:
------------------------
Traceback (most recent call last):
  File "/usr/lib/ubiquity/bin/ubiquity", line 212, in<module> main()

-------------------------

Now that I've typed all of that, the last line is probably the key--I'd tried the VM with only 2Gb of space allocated, evidently not enough. A more helpful error message or a available space check at the start of the install routine could be useful.
