*** This bug has been marked as a duplicate of 130630 ***
It says specificly that it shows the behavior _again_. this was fixed for 0.12.1, and _reoccured_ since the protocol was probably changed again, so it aint a dupe and it aint fixed.
and there we paddel back again, didnt read the full discussion on 130630. srz.
