The bug does appear again, So I think
spice-server-0.10.0-1.fc16.x86_64.rpm can fix.

The bug appear in my  software before, in steps  below:

1) virsh restore vm.ckp vm.xml
2) spice client connect
some time later go step 3)
3) virsh dump vm  vm.xml
4) virsh save vm vm.ckp
some time later go step 1) again

The err always appears in step 3) at random.

Anyway it is fixed.
Thanks,
