Bazaar 2.0.4 internal error

[Glenn Morris]

Using bzr 2.0.4 on a Debian testing system, I typed `bzr update' in my bound branch.
There was an internal error in Bazaar.

Here's the stuff from stdout/stderr:

> bzr update
bzr: ERROR: exceptions.ValueError: We are missing inventories for revisions: [('<email address hidden>',), ('<email address hidden>',), ('<email address hidden>',)]

This is a known issue, bug #437003
Run 'bzr pack' and things should be sorted out.

Thanks, it's ok again after `bzr pack'.
I never would have figured that out (as it says in the first comment in #437003).
FWIW, I did nothing unusual to cause this state (as far as I know);
just cycles of bzr update + commit.
