Honestly, me too.

I has discussed this issue with Till in the OpenPrinting Telegram group.

He told that best of all for Qt is to use the IPP-standard 
orientation-requested attribute instead of the CUPS-specific landscape 
attribute, but as Qt moves to CPDB, it is good enough just to use the 
landscape attribute correctly, as a temporary solution.

Seems tha Qt people have accepted out simple patch into master and plan 
to backport to older releases.

Yes, exactly. Actually, all current Qt programs are affected, not only 
okular.
