Hod did you get this one? I believe you use bad sandbox_web_client_t sandbox type. *** Bug 1041347 has been marked as a duplicate of this bug. *** I did have a firefox instance running inside a sandbox_web_t sandbox, but I thought this was outside the sandbox (on the desktop itself)? Not really sure how this one popped up. Could be a mix of resuming from suspend, asking g-o-a to sign into kerberos (on the desktop), not really sure. Also, setroubleshootd (along with journalctl) was taking 100% CPU for some reason for a really long while. Was burning up my battery pretty fast. amit are you seeing other AVC's? setroubleshoot sends avc messages to journal, so if you had an infinite amount of AVC's it could cause this problem. The sealert gui was only showing these three, but in a loop: by the time I delted one, there were 4 more added to the queue, and it was running continously. At that point, I tried kill -9 setroubleshootd, didn't work. There was no g-o-a process, so I was just trying to do something that would free up my CPU so that I could do something interesting. journalctl too was showing lots and lots repeated AVCs. I think I just did a pkill -SIGSTOP setroubleshootd, and filed these bugs and moved on. A pkill -SIGCONT setroubleshootd sometime later did not bring the erratic behaviour back.
Some text from journalctl around that time is pasted here

***** Plugin catchall (100. confidence) suggests **************************
If you believe that goa-daemon should be allowed read access on the key by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep pool /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
I counted something like 16 of these AVCs in one second. And this happened over several minutes.
