Indeed, regardless those should go on the ever growing list of ugly
error message issues :) I suspect at least some of the error
duplications which have been reported are caused by the fact that
python tasks both emit their messages directly to the user (not the
case for shell tasks, obviously), and to their log file, and the log
file is then shown to the user on failure. For the python case, either
the task shouldn't be able to output directly to the user, or we
shouldn't show their log on failure, I suspect.
