Summary:

SELinux is preventing /usr/sbin/nmbd access to a leaked /root/.xsession-errors
file descriptor.

Detailed Description:

[nmbd has a permissive type (nmbd_t). This access was not denied.]

SELinux denied access requested by the nmbd command. It looks like this is
either a leaked descriptor or nmbd output was redirected to a file it is not
allowed to access. Leaks usually can be ignored since SELinux is just closing
the leak and reporting the error. The application does not use the descriptor,
so it will run properly. If this is a redirection, you will not get output in
the /root/.xsession-errors. You should generate a bugzilla on selinux-policy,
and it will get routed to the appropriate package. You can safely ignore this
avc.

Allowing Access:

You can generate a local policy module to allow this access - see FAQ
(http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385)
