Michael Greenly: Lucky for me it’s easy migrate from bzr to git using svn as an intermediary.

Based on the comment by Pietro, I should be able to do this directly now.

First, fetch a known bzr repository.

$ bzr get http://intertwingly.net/code/venus bzr-venus
Branched 118 revision(s).

Then initialize a git repository.

$ mkdir git-venus
$ cd git-venus
$ git init
Initialized empty Git repository in /home/rubys/tmp/git-venus/.git/
$ cd ..

Now attempt the push.

$ cd bzr-venus
$ bzr dpush ../git-venus
bzr: ERROR: exceptions.AssertionError: type was None                           

*** Bazaar has encountered an internal error.  This probably indicates a
    bug in Bazaar.  You can help us fix it by filing a bug report at
        https://bugs.launchpad.net/bzr/+filebug
    attaching the crash file
        /home/rubys/.cache/crash/bzr-20100513190316-5624.crash
    and including a description of the problem.

    The crash file is plain text and you can inspect or edit it to remove
    private information.

Try Michael’s approach, using svn as an intermediary:

$ svnadmin create --fs-type fsfs svn-venus
$ cd bzr-venus
$ bzr push ../svn-venus
Initialising Subversion metadata cache in /home/rubys/.cache/bazaar/svn/0217a4d8-8507-45f3-96a1-39a8aa88a6d6.
