Jon Ericson asked me to report this (apparent) bug.
When he tried to protect this question someone (or something) stole the question's protection, which has since been missing:
The question shows no sign of having the protection removed, thus I believe it was abducted. I am sure justice will be done, and this poor question will receive the protection it deserves.
I recommend interrogating the little bird that was said to have announced this question to the world, I bet it would have some useful information.
