Occasionally I've been getting email notifications of a comment/trackback that winds up in my moderation queue qhich is obviously spam. Yet when I go to delete it, I get an error:
"Ooops, no comment with this ID"
My moderation queue is empty and the comment doesn't even exist in my spam folders as monitored by Akismet. It's weird. Anyone else ever seen this and found the reason why this happens?
