Apps don't start if click packages update without version number bump

Have some apps installed which are pre-installed and updated via the store.
Update phone with new software which includes the same version as the latest version in the store.
Note that said apps no longer start.
You may see the following in "dmesg -t | grep DEN"

[Wed Mar 12 18:02:23 2014] type=1400 audit(1394647344.351:243): apparmor="DENIED" operation="open" parent=1917 profile="com.ubuntu.calendar_calendar_0.4.201" name="/opt/click.ubuntu.com/com.ubuntu.calendar/0.4.201/calendar.qml" pid=2982 comm="qmlscene" requested_mask="r" denied_mask="r" fsuid=32011 ouid=104

The work around is to run:-

sudo aa-clickhook -f

Steps to reproduce:-

# Wipe phone and install clean
ubuntu-device-flash --channel=trusty-proposed --wipe --revision=226
# Grab a the click package (attached to this bug) which matches the version in the above rev of the phone
wget http://popey.mooo.com/mirror/clicks/2014-03-09-100001/com.ubuntu.calendar_0.4.201_all.click
# Install it
pkcon install-local com.ubuntu.calendar_0.4.201_all.click
# Note versions installed match:-
/usr/share/click/preinstalled/com.ubuntu.calendar/0.4.201
matches
/opt/click.ubuntu.com/com.ubuntu.calendar/0.4.201
# Start the app via the dash
# Observe white screen and above error in dmesg.
