Gtk/Gnome apps are unstable with Opensuse 13.1 kde

Hi all,

I'm running OS 13.1 KDE with nvidia graphics (x11-video-nvidiaG02) and have noticed that Gtk/Gnome apps are seriously unstable.

I use gnucash and it's obviously not working properly, it crashes regularly with a segfault. I attempted to use gparted to reformat a usb stick and it crashed. Libreoffice looks terrible under OS 13.1 kde, the fonts are mangled in the menu.

Any ideas how to sort this out?

Thanks for any help.
