'mark' buttons of non-kde applications in kde

Dear all,

I seem to have messed up my config a little. A few days ago I changed my
font selections (appearence) in control centre. Now my non-kde
applications don't 'mark' the selected button any more. The attached
screen shot shows that 'print' is marked, and so I can navigate with
'tab' to the correct button and hit enter (without touching my mouse).

This suddenly does not work for non-kde applications (iceweasel, etc.)
any more. How can I get it back, short of deleting all my profile?

Thanks,
Johannes
