This crash started to occur with this commit: http://bazaar.launchpad.net/~unity-team/unity/trunk/revision/3671

After some analysis, this exposed a latent bug in Nux. As such, opening tasks for Nux and will be getting a fix proposed soon.

im having issues with my compiz. im somewhat new to ubuntu and am on 14.04. I was on 13.10 and upgraded after having issues where my ccsm wouldnt open and its a consistant crash. I cant figure out why it wont open and is 100% crash all the time. i even went to the point where i reinstalled every app that i thought was involved and it did nothing to help. I just want to be able to run ccsm and enjoy a more interactive interface, as well as learn about ubuntu and continue on. Would appreciate it you could help fix this and help me understand how to fix this if the problem continues. thank you.
