Title:
  aa-logprof attempts to read program binary instead of profile

Status in apparmor package in Ubuntu:
  Fix Released
Status in apparmor source package in Trusty:
  Fix Released

Bug description:
  [impact]

  This bug makes it difficult for trusty users to use the apparmor policy
  utilities.

  [steps to reproduce]

  See below

  [regression potential]

  This issue is being addressed by updating the python utilities to the
  version in apparmor 2.9.2 as tracked in bug 1449769. This represents are
  large change which would normally be risky; however, these changes are
  isolated to the python utils (so no changes to the policy parser/loader
  or enforcement), there are a large number of bugs that exist in the
  trusty version that make using the tools difficult, so it would be
  difficult to regress further, and the updated version includes many new
  unit tests to try to prevent from regressions from occurring.

  [additional info]

  The python utils testsuite is run as part of the test-apparmor.py test
  script in lp:qa-regression-testing. The test-apparmor.py also has
  additional basic usage tests to ensure that basic functionality is
  maintained. These tests are run as part of the process fro each kernel
  update.

  [original description]

  $ aa-logprof -f aadenylog
  Reading log entries from aadenylog.
  Updating AppArmor profiles in /etc/apparmor.d.

      line = self.readline()

      data = self.read(readsize, firstline=True)

      newchars, decodedbytes = self.decode(data, self.errors)
  UnicodeDecodeError: 'utf-8' codec can't decode byte 0xab in position 25: invalid start byte

  The 'reading' output line is debug output added by me, printing
  prof_path just before line 180 (which is also why the line numbers may
  not match exactly). My assumption is that it is supposed to be reading
  '/etc/apparmor.d/usr.lib.chromium-browser.chromium-browser' instead.
