Thank you for taking the time to report this bug and helping to make
Ubuntu better. We are sorry that we do not always have the capacity to
look at all reported bugs in a timely manner. There have been many
changes in Ubuntu since that time you reported the bug and your problem
may have been fixed with some of the updates. It would help us a lot if
you could test it on a currently supported Ubuntu version.

When you test it and it is still an issue, kindly upload the updated
logs by running only once:

apport-collect 1602910

and any other logs that are relevant for this particular issue.

Hello. I've had the same message/error today. It seems, that the
"plugin-container" profile was responsible (which, I created today).
But, there was not any entries in the log files such as
`/var/log/kern.log` or `/var/log/syslog`. Everything was OK: for example
putting profile in the "enforce" mode etc. Message has shown after
enabling Firefox (by clicking on an icon).

So, I decided to remove the "plugin-container" profile, reload AppArmor
and Firefox profile (because there must be added one rule related to
plugin) and everything started to work normally. I have e10s enabled, a
couple of plugins installed etc. I've never saw such error.

Firefox ver.: 50.1.0
Flash ver.: 24.0.0.194ubuntu0.12.04.1 

Best regards.
