Jens,
I don't know if you had pulled this git tree yet (I don't see it in
your for-3.10/* branches).

But if you have, Sander has found a bug (and Roger has a fix for it).

Whether you would like to wait until v3.11 to pull it (and me sending
the git pull around a month) is OK. Or pull it now and we will fix the
bugs in the -rc's as they creep up.

Thanks!
