Description Bruce Drake 2008-01-10 18:12:12 EST
Description of problem:

    SELinux is preventing /usr/bin/nautilus (unconfined_t) "write" to <Unknown>

Detailed Description
    SELinux denied access requested by /usr/bin/nautilus. It is not expected
    that this access is required by /usr/bin/nautilus 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
    Sometimes labeling problems can cause SELinux denials.  You could try to
    restore the default system file context for <Unknown>, restorecon -v
    <Unknown> If this does not work, there is currently no automatic way to
    allow this access. Instead,  you can generate a local policy module to allow
    this access - see http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385
    Or you can disable SELinux protection altogether. Disabling SELinux
    protection is not recommended. Please file a
    http://bugzilla.redhat.com/bugzilla/enter_bug.cgi against this package.
