[Bug 986550] Re: Ubiquity crashes with "Illegal instruction" right after starting the slideshow

Hello ,

The crash occurs when a plein installation runs, right after reaching the slideshow.
"The installer encountered an unrecoverable error. A desktop session will now be 
run so that you may investigate the problem or try installing again."

Title:
  Ubiquity crashes with "Illegal instruction" right after starting the
  slideshow

Status in “ubiquity” package in Ubuntu:
  Confirmed

Bug description:
  Doing test installs on 6 different physical machines here, only one is
  giving me trouble installating.

  The crash occurs right after reaching the slideshow, it's 100%
  reproducable and the crash shows up as an Illegal instruction error in
  the terminal.

  Removing the slideshow entirely worked around the issue, so I'm
  strongly suspecting something wrong in webkit.
