apparently this is the upstream bug in bzr: https://bugs.launchpad.net/bzr/+bug/541626 which at time of writing remains unresolved

[pwaller]

Minimal(ish) script to reproduce (from scratch):

#! /usr/bin/env bash
set -u -e

mkdir test-bzr
cd test-bzr

bzr init
echo start >> test
bzr add test
bzr commit -m "Bzr commit"
bzr push lp:~/+junk/test-0

cd ..

git bzr clone lp:~/+junk/test-0 test-git
cd test-git
echo test0 >> test && git commit -am "git Update 0"
git bzr push
echo test1 >> test && git commit -am "git Update 1"
git bzr push lp:~/+junk/test-1
echo test2 >> test && git commit -am "git Update 2"
git bzr push lp:~/+junk/test-2

just wanted to point out that comment 38 from https://bugs.launchpad.net/bzr/+bug/541626 fixed it for me. which is fine. i don't need graphing at this time

The fix has also been added bzr-fastimport 0.13.0-4 in Ubuntu Trusty / Debian testing.
