That looks like a bug.

Try capturing the output of:

  $> strace -f -ttt qemu-kvm -M pc -m 768 -smp 2 -drive file=/var/lib/libvirt/images/Windows-XP-SP3-Home.img -net nic,macaddr=54:52:00:7e:1c:92,model=virtio -net user -serial pty -parallel none -usb -usbdevice tablet -vnc -usbdevice host:1d6b:0002 -monitor stdio > t.log 2>&1
