"Revision not present" when trying to resume a broken branch

[Ben Finney]

Howdy all,

I'm trying to branch <URL:http://bzr.bugseverywhere.org/be> into my
local repository, '~/Projects/debian/bugs-everywhere/'.

When I first tried doing this, I had an interruption of service and
the 'bzr' process was killed during the branch operation. (I don't
have any record of the error.)

Now, when I try again to branch into that same location, I get this
error:

    Revision {('abentley at panoramicfeedback.com-20060406165406-ff98c84f52a14683',)} not present in "<bzrlib.knit.KnitGraphIndex object at 0xf730f590>".

Yet if I branch from <URL:http://bzr.bugseverywhere.org/be> to some
location *outside* the repository, such as '~/be/', the branch
operation succeeds.

I can even 'rsync -a ~/be ~/Projects/debian/bugs-everywhere/be' and
use the resulting directory as a branch. But its revisions are not in
my repository (of course), and branching from that into my repository
still fails with the above error message.

Here is an example session:

How can I fix what is apparently broken in my repository?
