Description of problem:
Boot into Fedora-Live-Workstation-x86_64-rawhide-20160220.iso with enforcing=0.
SELinux is preventing evince-thumbnai from 'write' accesses on the sock_file bus.

*****  Plugin catchall_labels (83.8 confidence) suggests   *******************

If you want to allow evince-thumbnai to have write access on the bus sock_file
Then you need to change the label on bus
Do
# semanage fcontext -a -t FILE_TYPE 'bus'
where FILE_TYPE is one of the following: bumblebee_var_run_t, setrans_var_run_t, thumb_tmp_t, user_tmp_t. 
Then execute: 
restorecon -v 'bus'


*****  Plugin catchall (17.1 confidence) suggests   **************************

If you believe that evince-thumbnai should be allowed write access on the bus sock_file 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
