Comment 38 for bug 632696

Seeing this in Oneiric stock, as well as Oneiric with libvirt etc. from Precise.

Even tried ln -s /etc/apparmor.d/usr.sbin.libvirtd /etc/apparmor.d/disabled to no avail.

Seems to focus on opening a fd and pt_chown'ing it:

Remedy would probably be massaging apparmor, but I lack the fu to do so :-$
