Duplicated error messages

Duplicated error messages

I just ran 'bitbake core-image-minimal' on a new machine, running a fresh install of
Fedora 15.  I got some errors at the start about missing pieces, but the build carried on:
   ERROR:  Poky's config sanity checker detected a potential misconfiguration.
     Either fix the cause of this error or at your own risk disable the checker (see sanity.conf).
     Following is the list of potential problems / advisories:

     Please install following missing utilities: help2man,texi2html,hg,chrpath

Fair enough, I'll install those.  As I said, the build carried on, but failed
with a pretty useless error, log attached.  Notice how every line is duplicated,
plus there is not enough information to tell what file caused the error of
'No such file or directory'

Note: this was on Poky master 484c4e73245c93a08413cd204513bf5c5698b994,
updated this morning.

This is my fault -- at least, the continuing on is. As a part of
working on improving the exception handling in bitbake, the behavior
of exceptions in event handlers was changed.  We should likely change
it back for the SystemExit case, or add a more explicit method for
event handlers to communicate with bitbake proper. Sorry about that.

Thanks.  Even if this is not the desired behaviour (bitbake used to just quit
at the start when this happened), it is pointing out two other problems;
the duplicated error messages (I'd look for why this happens, but I really
wouldn't know where to start) and the less than helpful Python traceback.

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.
