Bug description:
  From bug #1351041:
  [Thu Jul 31 21:04:20 2014] type=1400 audit(1406837062.464:97): apparmor="DENIED" operation="chmod" profile="com.ubuntu.reminders_reminders_0.5.203" name="/run/user/32011/" pid=12954 comm="reminders" requested_mask="w" denied_mask="w" fsuid=32011 ouid=32011

  From irc:
  Aug 21 15:47:20 ubuntu-phablet kernel: [  251.843308] type=1400 audit(1408636040.346:137): apparmor="DENIED" operation="chmod" profile="com.ubuntu.camera_camera_3.0.0.355" name="/run/user/32011/" pid=4172 comm="camera-app" requested_mask="w" denied_mask="w" fsuid=32011 ouid=32011

  AppArmor policy is correct on this denial-- apps should not be able to
  change the permissions on the /run/user/32011/ (XDG_RUNTIME_DIR)
  directory. I filed this against camera-app and reminders, but my guess
  is this is an underlying library that is causing this. I don't know if
  the denial is causing errors with the app, but it is causing confusion
  for users and developers who see the denial.
