Bug 561905

Summary:

SELinux is preventing /usr/libexec/gdm-session-worker "getattr" access on
/tmp/.X11-unix/X0.

Detailed Description:

[SELinux is in permissive mode. This access was not denied.]

SELinux denied access requested by gdm-session-wor. It is not expected that this
access is required by gdm-session-wor and this access may signal an intrusion
attempt. It is also possible that the specific version or configuration of the
application is causing it to require additional access.

Allowing Access:

You can generate a local policy module to allow this access - see FAQ
(http://docs.fedoraproject.org/selinux-faq-fc5/#id2961385) Please file a bug
report.
