Comment 50 for bug 1659988

Hello Thomas. Yes, I think you're right; "Apparmor log messages sometimes occur for special tasks." By the way - today I have again an issue (this is happening very often) with the plugin-container (Chrome_ChildThr) segfault. Suddenly, Firefox started to slow down, system also, audio was looping and a mouse moved slowly. After a long while I managed to open terminal and kill Firefox process.

Log file - /var/log/syslog - was full of a known alsa-sink issue. There was also plugin-container (Chrome_ChildThr) entry:

✓ kernel: [24658.609247] plugin-containe[4287]: segfault at 0 ip 800128a8 sp bfdc2430 error 6 in plugin-container[8000f000+1c000]

And... there was also - mentioned in my post #45 - a "/usr/bin/speech-dispatcher" entry! It showed up once again. I was advised that I should create a profile for "speech-dispatcher" and use "Px" rule in a Firefox profile to address this DENIED entry.

However, here is a link to my bug report about plugin-container issues: <https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1656065> All of this is happening on 16.04.2 LTS Release and Firefox 53.0.2 version. I would like to ask: does any of you experienced this problem? I mean: Firefox, system, mouse freeze and a plugin-container segfault?

Thanks, best regards.
