>Detailed Description
>    SELinux is preventing /usr/libexec/gconfd-2 (xdm_t) "unlink" to <Unknown>
>    (var_lib_t). The SELinux type var_lib_t, is a generic type for all files in
>    the directory and very few processes (SELinux Domains) are allowed to write
>    to this SELinux type.  This type of denial usual indicates a mislabeled
>    file.  By default a file created in a directory has the gets the context of
>    the parent directory, but SELinux policy has rules about the creation of
>    directories, that say if a process running in one SELinux Domain (D1)
>    creates a file in a directory with a particular SELinux File Context (F1)
>    the file gets a different File Context (F2).  The policy usually allows the
>    SELinux Domain (D1) the ability to write, unlink, and append on (F2).  But
>    if for some reason a file (<Unknown>) was created with the wrong context,
>    this domain will be denied.  The usual solution to this problem is to reset
>    the file context on the target file, restorecon -v <Unknown>.  If the file
>    context does not change from var_lib_t, then this is probably a bug in
>    policy.  Please file a http://bugzilla.redhat.com/bugzilla/enter_bug.cgi
>    against the selinux-policy package. If it does change, you can try your
>    application again to see if it works.  The file context could have been
>    mislabeled by editing the file or moving the file from a different
>    directory, if the file keeps getting mislabeled, check the init scripts to
>    see if they are doing something to mislabel the file.
>
>Allowing Access
>    You can attempt to fix file context by executing restorecon -v <Unknown>
>
>    The following command will allow this access:
>    restorecon <Unknown>
