bzr log fails with KeyError: 'null:'

[Tom Cato Amundsen]

After upgrading from bzr 1.2 to 1.3, I have problems with "bzr log". --short or --line works fine, but --long gives this traceback.
The solfege repo was created with the tool that converted my gnu arch repo to bzr.

bzr branch http://www.solfege.org/bzr/solfege.dev

Using bzr 1.3 on some of my other repos, that are not converted from gnu-arch works fine.

I'm tca on #solfege and #bzr irc.

Confirmed here locally.

Showing the log using bzr missing works:
 bzr missing --long --reverse --mine-only ../solfege-3.10

[John A Meinel (jameinel)]

get_revision_graph has been removed in the latest versions. I'm not sure if that makes this a duplicate of bug #235055, just applicable to older bzr clients.

[Tom Cato Amundsen (tca)]

I'm closing this bug since the traceback mention in the report does not happen in bzr.dev.
(Opened a new bug https://bugs.launchpad.net/bzr/+bug/240795 with a different error, still trying to make latest bzr work with gnu solfege repo)
