That's a good place to ask about AppArmor related issues.

Most of the development related to AppArmor is done in the Gutsy
Gibbons, the next release of Ubuntu.

Gutsy has better integration of AppArmor: the AppArmor module is
packaged with the kernel, thus no manual compilation is required.
AppArmor is also loaded much earlier during the boot process from the
ram disk.

Are you talking about bug 113887 in launchpad ? If so, this bug has
been fixed in Gutsy, in release 0ubuntu6. Feisty has only 0ubuntu4.

Could you try to rmmod the capability module, then modprobe apparmor :
$ sudo rmmod capability
$ sudo modprobe apparmor
