I am wondering if this is intentional behaviour to keep the "normal" caller happy or
a just make it work situation. For now the only "reliable" option left to catch errors is
to parse the actual response for any traces of errors or exceptions.

Background: I am running a post-commit hook (svn) to automatically checkin
commits to MantisBT with a POST to checkin.php. So there I need a safe way to
inform the client (exitcode, message, mail,...) if the checkin really happened.
