[opensuse] KDE plasma crashes on login

Hi all, Just upgraded my O/S from 12.2 to 12.3 and on login KDE plasma crashes leaving me with a black screen. I rebooted into recovery mode, flipped into a terminal and moved .kde4 folder to .kde4-old so it would create a new one upon login. It successfully created a new desktop but plasma still crashes and no panel nor icons etc. My setup is Dell XPS L502x 8GB RAM Opensuse 12.2 I downloaded the iso and switched off all other repos and mounted the 12.3 iso and then ran zypper dup to get to where I am. Any help with plasma crashing on login would be appreciated Jide Sent from my BlackBerry® smartphone provided by Airtel Nigeria.
