I am seeing this about once a day. It happens after a compiz crash - when it happens, unity tries to restart but the launcher and panel don't appear.
Just now I tried the suggestion in comment #21 (ie from a root tty, kill the X session and do "killall -SIGABRT lightdm; start lightdm"), but it didn't work - after restarting the X session the problem persisted. I had to completely reboot the machine to fix it.
Since this bug is marked fixed, should we open another one?
