Comment 3 for bug 1393206

It looks like apparmor isn't allowing the mount.

[ 7963.575900] audit: type=1400 audit(1416145652.685:70): apparmor="DENIED" operation="mount" info="failed mntpnt match" error=-13 profile="/usr/lib/lightdm/lightdm-guest-session" name="/run/user/127/gvfs/" pid=7101 comm="gvfsd-fuse" fstype="fuse.gvfsd-fuse" srcname="gvfsd-fuse" flags="rw, nosuid, nodev"

I'm not sure which package is really to blame here, but I'm pretty sure it isn't the kernel. I'm changing this to affect apparmor, as I'm guessing someone there ought to know which package has actually caused this to regress.
