Comment 3 for bug 1319829

That looks like a problem with reading your profiles.

Can you please attach your /etc/apparmor.d/ (as tarball)?

If you don't want to upload all your profiles, you can edit aa.py and add (above line 2700):
    print(file, profile, hat)
This should print out which profile and hat is currently being read - the last one above the backtrace should point out the profile causing the problem. Please upload at least this profile.
