I think this is

  https://bugs.launchpad.net/bzr/+bug/202884

The traceback in that bug shows it failing inside generate_root_texts
while upgrading, while doing check_versions_present.

KnitGraphIndex needs a more useful repr, showing just what object it
was trying to look in.  First off you should patch that and submit it
separately; it will help with this and similar bugs.

generate_r_i is trying to generate new inventories depending on the
particular root id, and it's failing to add that text because on of
the parents is not present.  This may be because they have a revision
where the root id changed?

For that revision and its parent revisions, what are their root ids?
(I don't know off hand precisely how the conversion works but I would
start there.)
