When doing a standard workstation install, I set everything up to the 
point of having it start formatting the drive i was installing it on (a 
10K RPM WD 9.1GB Ultra160 SCSI HDD).  It hung for a LONG time on 
formatting the /boot partition (sda1) and then exit out giving an option 
to save the bug to post here.  Here is a raw copy of the text file it made:

Traceback (innermost last):
