Plasma (ALWAYS) crashes on shutdown

I’ve got suse 11.0 here with KDE 4 of some variety. Ever since I installed suse (several months ago), whenever I shut down the computer (every night) I get a message telling me that Plasma has crashed with signal SIGSBRT. That’s all the box tells me. I just have to click “close” and shutdown continues, but it’s getting annoying. Any idea on how to fix it?

Thanks,
Dan

Make sure that no application is running before shutdown. Especially kopete and kontact.
