A different problem with the new xen 3.0.2 package

After upgrading to the new kernel and xen userspace packages, I'm  
seeing this in my xend.log when I try to start it:
[2006-10-21 09:37:24 xend 2674] INFO (SrvDaemon:283) Xend Daemon started

Interestingly (?) my normal xend processes remain running, even if  
xend doesn't seem to be working:
