Version:           Version 1.0 KDE 4.3.4 "release 2" (using KDE 4.3.4)
OS:                Linux
Installed from:    openSUSE RPMs

I run KDE 4.3.4 which I installed from the Opensuse repositories (stable branch). My system is an Opensuse 11.2 system on a x86_64 architecture with a quad core intel processor and an Nvidia graphics card (9800 GTX+).

There were no problems with "system settings" in the original KDE 4.3.1 version, which was installed with Opensuse 11.2. I could click on "display" and get some information about my screen. 

However, after an upgrade to KDE 4.3.4 and the installation of the proprietory nvidia drivers "system settings" crashes as soon as I click on the "display" icon on the main window of the system settings dialog. 

I never had this problem with KDE 4.3.1 (together with the nvidia drivers) on an Opensuse 11.1 system. 

Crash infos from the system:
