I tried searching in the sourcecode for the piece of code that is being displayed, it looks a bit like it's part of the unpublish() method showing through from cms/code/CMSMain.php (lines 714 - 718), but a bit different.
What version of SS are you running?
Are you sure nothing went wrong? Maybe missing pieces during upload? Tried flushing?
Or it might be some custom code with an error in it?
