Thanks, but you were a bit too fast ;-)

dbus.cc was fixed upstream some days ago (exactly in the way you fixed
it), and for af_rule.cc there's a patch pending that is very similar
to your patch:
https://lists.ubuntu.com/archives/apparmor/2015-February/007205.html
which will be commited soon.

Anyway, I'll accept your patch for now and replace it with the upstream
version when 2.9.2 is released.
