Description of problem:
SELinux is preventing /usr/bin/evince-thumbnailer from 'append' accesses on the unix_stream_socket unix_stream_socket.

*****  Plugin leaks (86.2 confidence) suggests  ******************************

If you want to ignore evince-thumbnailer trying to append access the unix_stream_socket unix_stream_socket, because you believe it should not need this access.
Then you should report this as a bug.  
You can generate a local policy module to dontaudit this access.
Do
# grep /usr/bin/evince-thumbnailer /var/log/audit/audit.log | audit2allow -D -M mypol
# semodule -i mypol.pp

*****  Plugin catchall (14.7 confidence) suggests  ***************************

If you believe that evince-thumbnailer should be allowed append access on the unix_stream_socket unix_stream_socket 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 evince-thumbnai /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
