I have the 2.9 package but this bug still seems to affect me:
ii apparmor-utils 2.9.2~2880-0ubun amd64 Utilities

# aa-logprof

Title:
aa-logprof: Log contains unknown mode senw
Status in AppArmor Linux application security framework:
Fix Released
Status in apparmor package in Ubuntu:
Fix Released
Bug description:
[Impact]
* aa-logprof does not work when dbus rule denials are present in the
logs
[Automated Test Case]
* test_lp1243932_send, test_lp1243932_receive, and test_lp1243932_bind
have been added to QRT's test-apparmor.py test script
[Manual Test Case]
* Load a profile that does not grant D-Bus access and create a D-Bus denial.
Then,
test aa-logprof.
$ echo "profile lp1243932 { file, }" | sudo apparmor_parser -rq
$ aa-exec -p lp1243932 -- dbus-send --print-reply --system \
--dest=org.freedesktop.DBus /org/freedesktop/DBus
org.freedesktop.DBus.ListNames
Failed to open connection to "system" message bus: An AppArmor policy
prevents this
sender from sending this message to this recipient, 0 matched rules;
type="method_call", sender="(null)" (inactive)
interface="org.freedesktop.DBus"
member="Hello" error name="(unset)" requested_reply="0"
destination="org.freedesktop.DBus" (bus)
$ aa-logprof -f /dev/null
Reading log entries from /dev/null.
Updating AppArmor profiles in /etc/apparmor.d.
An unpatched aa-logprof will print similar output followed by:
Log contains unknown mode senw.
[Regression Potential]
* The regression potential is low since aa-logprof currently refuses to work
when D-Bus
denials are present. The fix is minimal and has been reviewed by upstream.
[Original Bug Report]
since saucy aa-logprof does not work anymore:
$ aa-logprof
Reading log entries from /var/log/syslog.
Updating AppArmor profiles in /etc/apparmor.d.
Log contains unknown mode senw.
the issues seem to be caused by dbus send denies:
Oct 23 19:52:56 ubuntu dbus[2594]: apparmor="DENIED"
operation="dbus_method_call" bus="session"
path="/org/freedesktop/DBus" interface="org.freedesktop.DBus"
member="Hello" mask="send" name="org.freedesktop.DBus" pid=3552
profile="/usr/bin/smuxi-frontend-gnome" peer_profile="unconfined"
23:16 <tyhicks> my guess is the denial of a dbus send
23:16 <tyhicks> senw is awful close to send
23:17 <tyhicks> parse_event() in AppArmor.pm does this:
23:18 <tyhicks> $rmask =~ s/d/w/g;
23:18 <tyhicks> followed by:
23:18 <tyhicks> fatal_error(sprintf(gettext('Log contains unknown mode %s.'),
$rmask));
