check: Missing key in get_sha1s

Latest bzr.dev (r4417 now, who knows what back on the 29th), Ubuntu.

A couple weeks ago, I tried to branch a copy of lp:~jelmer/loggerhead/smart-server (since deleted) into my local 1.9-rich-root shared repo. It turns out the branch was broken in some strange way. For example:

mnordhoff@cheezum:/tmp$ bzr branch --no-tree lp:~jelmer/loggerhead/smart-server
Branched 359 revision(s).
mnordhoff@cheezum:/tmp$ cd smart-server/
mnordhoff@cheezum:/tmp/smart-server$ bzr co
bzr: ERROR: No such file: ('servebranches.py-20080618011543-s6ydx5c3bl38zap6-1', '<email address hidden>')

Cool, huh? Anyway, just now I happened to run "check" on that repo, and thanks to that revision, it's not quite right anymore:

  File "/home/mnordhoff/co/bzr/bazaar/bzr/bzr.dev/bzrlib/inventory.py", line 497, in _check
    if (self.text_sha1 != tree._repository.texts.get_sha1s([key])[key]):
KeyError: ('wsgitest.py-20080612051902-5y0zpdi6fhxgun6z-1', '<email address hidden>')

So...what now? :D
