Description of problem:
Opening a video, plugin container failed due to selinux.
SELinux is preventing /usr/lib64/xulrunner/plugin-container from 'execute' accesses on the file /home/carlos/gnome/install/lib64/libgobject-2.0.so.0.3503.0.

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

If you believe that plugin-container should be allowed execute access on the libgobject-2.0.so.0.3503.0 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 plugin-containe /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
