compiz crashed with SIGSEGV in UnityScreen::~UnityScreen()

[Jeffrey Mikesell]

Again another WM crashes in 11.10, does any of them work? You state 11.10 I shoud install the oneiric-proposed release with one fix and the other in process. OK, I'll do it again, I started with the oneiric-proposed and I am unable to get any of the WM working I will flood you with bugs, and you can take that to the bank!

How many installs does it take to get a single function 11.10 system working with the ubuntu team 2*32-1
