Bug Description

Compiz/Unity is hanging when previewing an item with the smart scopes PPA. This is what I am doing:

 1. Open the dash.
 2. Search for 'Severed Fifth' in the home lens.
 3. Wait for the Code items to appear and right-click the 'Severed Fifth Fan App'.
 4. You should see the spinner and then it will stop spinning and Unity has hung.

When I did this the last time I got a gdb backtrace:
