I was updating through Xubuntu. I didn't know my environment was compositing through Compiz. This error occurred @ reboot.

Thank you for reporting this bug to Ubuntu. 11.04 reached EOL.
See this document for currently supported Ubuntu releases: https://wiki.ubuntu.com/Releases

Please upgrade to the latest version and re-test. If the bug is still reproducible, increase the verbosity of the steps to recreate it so we can try again.
