This looks like the thumnail driver is strying to write to a sock_file ownered by syslog?
Comment 2 David Hill 2017-06-09 11:08:02 EDT
Yeah I don't understand why it would want to do that.
Comment 3 Daniel Walsh 2017-06-09 11:11:21 EDT
Probably sending a syslog message.  But I am not sure we want thumbnailers writing to syslog.
Comment 4 David Hill 2017-06-09 11:13:45 EDT
Perhaps it should be dont audit then...  We can always turn on all dont audit with semodule I thin.

This bug appears to have been reported against 'rawhide' during the Fedora 27 development cycle.
Changing version to '27'.
