Thanks for the bug report! This is a duplicate of bug #1216294.

There's no need to test mainline, as Joseph asked you to do. This is
caused by an AppArmor patch that is specific to Ubuntu and not yet
upstream.

The tip on 512MB RAM server VMs will be helpful. I'm setting up such a
VM right now. Thanks again!
