I'm currently in a situation where I don't have easy accesss to my
regular environment, but I'm getting failures when running the tests
with python2, like so:

 ERROR: test_44306 (__main__.TestParseParserTests) test '{'exresult': u'PASS', 'tools_wrong': False, 'relfile': 'rlimits/ok_rlimit_01.sd', 'disabled': False, 'file': '/home/steve/bzr/apparmor/parser/tst/simple_tests/rlimits/ok_rlimit_01.sd', 'todo': False}'

    apparmor.parse_profile_data(data, params['file'], 0)
  File "/home/steve/bzr/apparmor/utils/apparmor/aa.py", line 2690, in parse_profile_data
  File "/home/steve/bzr/apparmor/utils/apparmor/rule/__init__.py", line 73, in parse
    rule = cls._parse(raw_rule)
  File "/home/steve/bzr/apparmor/utils/apparmor/rule/rlimit.py", line 135, in _parse
  File "/home/steve/bzr/apparmor/utils/apparmor/rule/rlimit.py", line 66, in __init__
    raise AppArmorBug('Passed unknown object to RlimitRule: %s' % str(rlimit))
AppArmorBug: Passed unknown object to RlimitRule: cpu


I don't *think* it's due to a quirk in my setup. With python3, it passes
all tests.

(Granted, I would like to deprecate python2 in 2.11, making python3
preferred, and then drop python2 support in 2.11+1.)
