unity_support_test crashed with SIGSEGV

[Enkouyami]

This Is related to bug 931129
Whenever I log-in with Unity 2D or 3D, the Unity dock doesn't appear, but the top panel is there with only the globalmenu. 1st it happened after a couple days of using Precise alpha 2. I installed the system 1 day after it was released. This Happens with nvidia(version current) and nvidia(version current)(post release updates). I can now reproduce it just by freshly installing it on a new partion with updates selected from the ubiquity installer. I don't know if it happens when if I don't have select to get updates during the installation process and after I installed it. Each time I tried to install Precise with isos from http://cdimage.ubuntu.com/daily-live/current/precise-desktop-i386.iso
I just noticed that unity works after I installed xubuntu-desktop. Im not sure if the packages in xubuntu-desktop did anything. Ill try to see if the same thing happens again after a fresh installation.
