Computer won't boot properly!

[darkwolfalone]

I upgraded to Kubuntu 8.10, installed Korean language support and set SKIM to start when KDE starts, and now KDE will not start properly. Please wonderful Ubuntu/Kubuntu community, save my life! I get the following error (I have no idea what it means):
