Top secret bugs?

[Scott Sloan]

Was poking around and posting a bug in mozilla and rhythmbox this
afternoon and preview some other bugs that looked interesting. This one
caught my eye primarily for what I can't see

https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=117908

Is this an bug in bugzilla or are their suppose to be bugs members can't
see for their protection? Or one really weird April Fool's joke?
