KDE Sysguard: Connection to localhost has been lost!
 

I upgraded to KDE 3.2 last week, and it's really good, excepting a few confusing things. One that really bothers me is that KDE Systemguard is not working - my system has hung a few times, and sysguard has previously been a good way of fixing things, but now whenever it starts it give the following error message: "Connection to localhost has been lost!" I can't get it to reconnect. Any ideas on how I can fix this?
Thanks.
