Comment 1 for bug 582426

Starting from the "Netbook 2D" version seemed to work, but I clicked on "Files->Documents" - and it appeared to get stuck in a loop opening Documents windows! Rebooting and opening the "Appearance" settings app seemed to work, but when I closed it, the launcher was also gone and I was left with a standard Gnome desktop.

I don't know if it is relevant or not, but if I try the "Unity" manager it just hangs before coming up.
