Comment 5 for bug 761368

Quick follow-up

Unity never started up correctly after this error.
Top bar and side launcher never loaded.
Keyboard commands (Alt-F2) did not work either.
Only function was right-click, create custom launcher (which opened a firefox window that could not be closed).

Ubuntu "classic" would also load incorrectly
Every open window did not have a top window bar (Close, Min, Max).
All windows were stuck in the top left corner of the screen.
Desktop workspace switcher did not function.

This was in a partition that I regularly use, so I wiped and re-installed 10.10
Let me know if you need me to try to re-create.
