Description of problem:
In a text mode install, the installer crashes while trying to update
the progress bar due to a divide by zero error. More frightening, however,
is that the python interpreter doesn't appear to always catch the
divide-by-zero, as on another occasion, the installer died in a signal 8.

How reproducible:
Sometimes - it sometimes works without crashing, other times very early.

Additional info:
Here's a python traceback.
