Yeah, that's a known bug and I believe is fixed in 1.3.5.
All it does is point to (IIRC) admin/moderation.php anyway.
There's an easy fix which I put on my site, but I don't recall
what it was :-) I think you edit admin/index.php and go
right to the bottom. YOu'll see a COM_refresh and all you
do is add "print" to the front of that line.
