Description of problem:
SELinux is preventing /usr/libexec/totem-plugin-viewer from 'write' accesses on the directory /etc/pki/nssdb.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that totem-plugin-viewer should be allowed write access on the nssdb directory 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 totem-plugin-vi /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
