[opensuse] "Accessing the Package Management Failed" in YaST

I'm getting a message "Accessing the Package Management Failed" whenever I try to start online update in yast. It tells me the pid of a non-existent packagekitd process which it claims is holding a lock. What do I need to do to recover? And what might have caused the problem?
