what to do with repo with ghost revision

[Tom Cato Amundsen]

The bzr repo of GNU Solfege was initially converted from a baz repo
(and that from a tla repo, I think).

As a result there are ghost revisions. And while you have fixed many
bugs related to ghosts, I have started wondering if I should create a
fresh repo with bzr 2.0 and abandoning old history. Right now there is
bug #397556 that make "bzr tag" only work on bzr 1.15 and older. And
if you fix that bug, history has shown that some other bug will pop up
and I'll start complaining again :-)

Do you think ghost revisions will ever be (almost) problem free for
bzr users? Are there any tricks I can use to keep some history and
loose the ghosts?
