"...though that might just be Suse's packaging or Gnome app running under unfavourable KDE settings..."
Yup - I had that one on Slackware with KDE 4.15. Slack does not install any Gnome libraries by default. There was a work around using a theme I recollect and some changes in the KDE config. I needed the oxygen-gtk2 engine installed and I had to puggle about disabling the LibreOffice KDE integration code. After that it looked toastie.
I'd ask on an OpenSuse forum for specifics.
