I'll try to find your bug the next days (in case you find anything let

At the very least, this will be necessary:

       key_sa_recordxfer(sav, m);

But it doesn't fix the problem.

That fix was committed to HEAD. Thanks!

In addition to that can you try this patch:

I have to admit, I haven't tried it after my last merges so I hope I
got the merges right;-)

Software is harder than hardware  so better get it right the first time.
