Description of problem:
after logging into root user when i tried to access properties of a folder containg media files,it showed permission denied 2 times simultaneously,then the window closed.plz help.
SELinux is preventing /usr/bin/evince-thumbnailer from using the 'dac_override' capabilities.

*****  Plugin dac_override (91.4 confidence) suggests  ***********************

If you want to help identify if domain needs this access or you have a file with the wrong permissions on your system
Then turn on full auditing to get path information about the offending file and generate the error again.

Turn on full auditing
# auditctl -w /etc/shadow -p w
Try to recreate AVC. Then execute
# ausearch -m avc -ts recent
If you see PATH record check ownership/permissions on file, and fix it, 
otherwise report as a bugzilla.

*****  Plugin catchall (9.59 confidence) suggests  ***************************

If you believe that evince-thumbnailer should have the dac_override capability by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# grep evince-thumbnai /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
