FWIW this seems to occur about 1 - 2 minutes after logging in.

There are several AppArmor messages that seem to preceed this event in dmesg, for example

This happens every time I use both my desktop and my laptop. This is extremely annoying!

Same thing happens to me a few minutes after I log in...
