Hmm, well that stops the output and leaves me with a blank page (no HTML or
anything.)  The URL contains the correct address though (of my Special page,
it hasn't changed to the URL of the last page edited.)

I wonder why the output doesn't seem to get enabled again after restoring
$wgOut?  No errors about headers or anything being set already...

Cheers,
Adam.
