We found a work around for this bug. http://askubuntu.com/questions/194596

Obiously an error with the webcam should not crash Ubiquity in this way.

This bug was fixed in the package ubiquity - 2.13.17

---------------
ubiquity (2.13.17) raring; urgency=low

  * Remove webcam step (LP: #1118589):
    - User testing showed people are not expecting to be photographed and
      raise privacy concerns as to where the picture will be uploaded to.
    - Provides limited benefit, as avatar only ever shown on multi-login
      systems in the switch user indicator / pkexec.
    - Crashes the installer or doesn't work with certain webcams.
    - Miss detects camera presence, when it's just a sensor.
    - The recommendation is to move webcam test to checkbox / hw testing,
      as video conferencing is very popular these days and should work
      reliably out of the box.
    - LP: #924419 , LP: #981644 , LP: #987392, LP: #1152254, LP: #843354,
      LP: #1008204, LP: #1021449, LP: #1082458, LP: #1103780, LP: #1142751
  * Do not count optional pages, when updating the progress dots. This
    fixes "Porgress dots, well don't progress after partman step"
    LP: #1152746
  * Do not mark explanatory text on "Installation Type" screen
    insensitive, as otherwise it's ineligible (LP: #1074386)
