Revert <a href="http://websvn.kde.org/?rev=706570">r706570</a>; which fixed a corner case in kaffeine and broke zoom settings on kpdf, kghostview, kview and basically anything using editable kselectations

You'll have to find a fix that does not break all the other applications using the same class as you

Please next time be extra careful when touching kdelibs code
