RFC: remove traceback from "newer branch format than your bzr"

And in addition I could point to some brilliant developers who just
don't want to be bothered with information they cannot realistically
be expected to act upon.
And tracebacks are more than enough to scary off documentation
specialists who need vcs but obviously are not coders.
Finally my biggest hurdle. if a manager ever hears about something
that sounds unstable (he does not even need to see it for himself. A
Managers job is to make safe decisions based on incomplete data!) it
could be enough to stop bzr adoption in its tracks. I am having this
FUD is a real effect. The svn team seem to understand this and have
made it very unscary to nondevelopers. I believe this is an important
"hidden" source of their success. So far none of the dvcs systems
have perfected this... Which means it is still an opportunity for bzr
to distinguish itself as a leader in the user experience.
