Yes, I ran into this running Kubuntu 8.10 under vmware.  I googled around
and found a couple of potential fixes, one being a patch that was already
on, and the other an X system setting to restart X on logout which seemed to
work. I'm a little hazy on the detail now, but if you google "ubuntu
shutdown hang" I think you'll find quite a few folks have experienced it.
