Comment 9 for bug 246880

I tried to do this and got some way, but am now stuck. The current branch error is:

<cjwatson@sarantium ~/src/ubuntu/casper/bzr>$ bzr branch casper.backup junk
bzr: ERROR: Revision {Arch-1:<email address hidden>%casper--main--0--patch-9} not present in "x_Matt_Zimmerman_<email address hidden>_Sun_Mar_13_00:51:19_2005_1366.36".

I believe that I have imported that revision, although with some difficulty. fetch-ghosts refused to fetch it, I think because it was a direct ancestor, and I had to use bzrlib by hand to say this_branch.fetch(other_branch, 'Arch-1:<email address hidden>%casper--main--0--patch-26'). However, that succeeded (reporting 27 new revisions), so I proceeded to try to import the other branches that would supply the remaining ghosts.

My current attempts are failing like this. Relevant baz archives are:
