Any news about this? Please, I can't use Unity 3D because this. At any time my session is closed and ALL MY WORK IS LOST. I'm using now Unity 2D, and I tried other shells, but I really like Unity 3D. I always used Unity 3D (and Gnome2 + Compiz in the past) wihtout ANY issues in this machine.
How can I help with this?

Though if you're using the nvidia driver then this is probably a duplicate of bug 982485.

I'm sorry, I don't know how to "click through the dialogs" because there's none : my unity session just crashed without warning and I'm back to the login screen. Could you help me transfer some informations (maybe some logs ?) ?

Second day without a session crash. Seems to be related to bug #982485.
Still testing. Cross your fingers! ;-)

F*ck! Still crashing. After a few hours, my Unity 3D session crashed (or closed) again and send me back to login screen.
I was using Firefox 13.0 only this time, 4 tabs open. I was watching a youtube video on a tab when it crash, and I had two others tabs with youtube video too.
Except for this, Unity 3D seems to works great in this machine, but I can't use it for work, 'cause I can't risk to lost work.
In the past, I never had have issues with Compiz (Gnome 2) nor Unity 3D with this machine :(
