Bug 591999

Summary:

SELinux is preventing /usr/bin/xauth access to a leaked
/home/alex/.lyx/lyxpipe.in file descriptor.

Detailed Description:

[xauth has a permissive type (xauth_t). This access was not denied.]

SELinux denied access requested by the xauth command. It looks like this is
either a leaked descriptor or xauth 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 /home/alex/.lyx/lyxpipe.in. 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://docs.fedoraproject.org/selinux-faq-fc5/#id2961385)
