Bug Description
Was using Dash Home on unity to find a program and stopped typing and wanted to backspace. The lens froze up and I was not able to escape out of it or delete what I had typed. After about 45sec - 1 minute unity crashed and the compiz error was presented. Unity automatically restarted after that.
1. Using: Description: Ubuntu oneiric (development branch) Release: 11.10 beta 1
2. apt-cache policy compiz :
compiz:
Installed: 1:0.9.5.
Candidate: 1:0.9.5.
Version table:
*** 1:0.9.5.

apt-cache policy unity :
unity:

3. When typing in the Dash Home Search, when I stopped typing and hit the backspace key; I would expect the previous character of the search string to be erased, and the search results altered accordingly. I would also expect hitting the esc key would exit out of the Dash Home and return me to the desktop.
4. Instead Dash Home screen froze, I was no longer able to type anything and was unable to escape out of it. Eventually Unity crashed and produced the Compiz crash
