I experienced nearly exactly the same problem two days ago.
Also with *.44.

One big difference in my case:

I used a failing pvmove first:
	pvmove -v -i 10 /dev/sda6:0-20 /dev/sda6:100-120

Moving inside the same PV (for example to reduce
fragmentation) does not seem to be supported at all. I
usually have to do that by moving the PEs first to another
PV and then back.

Shouldn't the "operation" be done after the mirror has
finished? So that a power outage leaves LVM in the state
just before the pvmove and one can start over from the
