apparmor fails loading policy with nested profiles inside hats

To reproduce:

$ cat ~/tmp/test.profile
profile spork /t {
  hat waffle {
    /bin/sh Cx -> syrup,

    profile syrup {
      /bin/sh r,
    }
  }
}
$ sudo ./apparmor_parser -Kr ~/tmp/test.profile
./apparmor_parser: Unable to replace "syrup". Profile doesn't exist
$ sudo grep syrup /var/log/audit/audit.log
type=AVC msg=audit(1403737842.880:42591): apparmor="STATUS" operation="profile_replace" info="parent does not exist" error=-2 profile="unconfined" name="waffle//syrup" pid=874 comm="apparmor_parser"

This is with kernel Ubuntu 3.13.0-24.47-generic 3.13.9 (amd64)

It also fails similarly if not using a profile name, e.g.:

profile spork /t {
  hat waffle {
    /bin/sh Cx,

    profile /bin/sh {
      /bin/sh r,
    }
  }
}

results in:

type=AVC msg=audit(1403738004.360:42598): apparmor="STATUS" operation="profile_replace" info="parent does not exist" error=-2 profile="unconfined" name="waffle///bin/sh" pid=1807 comm="apparmor_parser"
