Bug Description

Ubuntu Oneiric 11.10 with last updates

1. Use Unity desktop on Oneiric
2. Set a wallpaper
3. Delete the wallpaper file
4. Close session and open it again

Unity will crash, and only show the desktop (without wallpaper/background, but if you have files inside te desktop, you can open them, this is how I could report this bug)

Finally I found this bug!

Unity in my Ubuntu account was crashing, but reading other Forums (in italian) I found that If you create another account, Unity works fine, and he was right, the new account works perfect.
So I made test changing different configurations of Unity/GNOME (change size of icons, activate zoom, activate opacity on Unity panel and Dash, change fontsize, set a wallpaper, etc). But I finally found the bug.

If you delete the wallpaper file used on your session, when you try again to login, Unity/Compiz crashed. I can reproduce this bug everytime.
