On Tue, Aug 11, 2009 at 04:20:26PM -0500 I heard the voice of
Neil Martinsen-Burrell, and lo! it spake thus:

I also get a gigantic pile of these in various impoverished-root repos
here.

In fact, it's reproducible from nothing.  Just 'init' a new tree, make
a commit, and run check:

% bzr init ; touch x ; bzr add ; bzr ci -m 'x' ; bzr check
Created a standalone tree (format: pack-0.92)
adding x
Committing to: /tmp/bzr/
added x
Committed revision 1.
Checking working tree at '/tmp/bzr'.
Checking branch at 'file:///tmp/bzr/'.
Checking repository at 'file:///tmp/bzr/'.
checked repository <bzrlib.transport.local.LocalTransport
url=file:///tmp/bzr/> format <RepositoryFormatKnitPack1>
     1 revisions
     1 file-ids
Missing inventory {('TREE_ROOT', 'fullermd at over-yonder.net-20090814070519-cvcc7o5ownckrjbi')}
checked branch file:///tmp/bzr/ format Branch format 6
