crash when screen woken up

[James Hunt]

In System Settings, I've specified "turn screen off after 10 minutes of inactivity. That works fine, but when I come to wake the screen up by pressing any key, the screen flashes furiously with windows moving around and between workspaces indicating that compiz/unity has crashed and is restarting.

Notes:

- This behaviour is fully repeatable.
- No crash file is written to /var/crash.
