bzr log fails with KeyError if there is a ghost in the mainline history

[Tom Cato Amundsen]

"bzr check" fails similarly. http://www.solfege.org/bzr/solfege.dev is on the net so you can see yourself.
The repository was created with the tool that converted my gnu arch repo to bzr (was it baz-import??)

I am uncertain if this bug is the same as https://bugs.launchpad.net/bzr/+bug/205564
If so, I'm sorry for the duplicate report.

Bzr 1.3 works fine.

Fails on bzr.dev too.

[Tom Cato Amundsen (tca)]

Sorry, one error in the initial report: works on bzr 1.2, not 1.3.
On bzr 1.3 the bug looks similar to https://bugs.launchpad.net/bzr/+bug/205564, so this is probably a duplicate.
