Gnome unstable on opensuse 3.10


After have been running opensuse 11.2 on Thinkpad T60p, I recently installed opensuse 13.1 with gnome 3.10 on my new T430s.

While the old setup was very stable, the new 13.1 installation is not.

Almost every day (and sometimes multiple times per day) the desktop crashes.

I have been trawling /var/log/messages trying to nail down what happens just before each crash, and this seems to be happening prior to each crash:

Not sure how to go forward from here.
Has anyone experienced such behaviour ?

Best regards

Subject is wrong, it is of course opensuse 13.1
