Description of problem:
SELinux is preventing /usr/bin/rhythmbox from 'name_bind' accesses on the tcp_socket .

*****  Plugin mozplugger (99.1 confidence) suggests  *************************

If you want to use the plugin package
Then you must turn off SELinux controls on the Firefox plugins.
Do
# setsebool -P unconfined_mozilla_plugin_transition 0

*****  Plugin catchall (1.81 confidence) suggests  ***************************

If you believe that rhythmbox should be allowed name_bind access on the  tcp_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 rhythmbox /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
