OK, figured that one out;  it was a cleanup path for the postcopy
notifier trying to remove the notifier when because we were testing a
failure path the notifier hadn't been added in the first place.

(That was really nasty to find, for some reason those tests refuse to
generate core dumps; I ended up with a while loop doing gdb --pid
$(pgrep....) to nail the qemu that was about to seg)
