Title:
  unity crashes with Bus Error when I enable my second monitor.

Status in “unity” package in Ubuntu:
  Triaged

Bug description:
  My Setup:

  Version: Ubuntu 13.10
  Video Card:  ATI Radeon 2600XT on Open Source Drivers (fglrx is unavailable for this card on 13.10)
  Montor #1@1920x1080  
  Monitor #2:@1440x900  on left of Monitor #1

  How to reproduce:

  Open "Displays" from the dash.  Select the secondary monitor.  Turn the secondary monitor off (in the settings, not the physical button on the monitor), and click "Apply."
  Close "Displays".  Reopen it.  
  Select the secondary monitor.  Turn the secondary monitor on (in the settings; not on the monitor, itself.) 
  Put the secondary monitor to the left of the primary monitor. 
  Click "Apply"

  
  Expected Results:
  Secondary Display turns on, and I am prompted to keep my settings or revert.

  Actual Results:
  Brief screen garbage, followed by unity crashing.  Whenever I try to resurrect Unity from a either VT or a terminal emulator running in X, I see "Bus Error (core dumped)".  This continues until I end my session.
