When trying to do a conversion from git to bzr, I ran into a problem and
it crashed early in the process. As I happened to spend the morning with
one of the Bazaar-NG hackers, Robert Collins, we paired on it for half an
hour and he quickly traced the source.
When the git importer runs, the first thing it does is clone the source
repository to a local checkout. However, a subsequent command, `git rev-
list HEAD`, breaks. Step debugging through, Robert discovered that rather
than the temporary clone, it was trying to use the old directory (and
wrongly at that - no /.git was joined) - in other words, `GIT_DIR=` was
set wrong.
Unfortunately he then started navigating all over the place so I'm not
sure precisely where it was he discovered the problem, but he did a hot
replace and it then succeeded (Well, for about 30 changesets (and then
some other bug snagged it. Alas) My suspicion is that he was in the
neighbourhood of lines 42-65 of `vcpx/repository/git/__init__.py`
I'm really sorry I can't be more precise, but hopefully that will spurn
investigation in the right direction.

The config file was whatever tailor generated with a very simple `tailor
-v -s git -R ~/workspace/SlashTime/ -t bzr -T ~/tmp/slashtime-bzr`:
{{{
[DEFAULT]
verbose = True
[project]
target = bzr:target
start-revision = INITIAL
root-directory = /home/andrew/tmp/tailor-data
state-file = tailor.state
source = git:source
subdir = .
[bzr:target]
repository = /home/andrew/tmp/slashtime-bzr
[git:source]
repository = /home/andrew/workspace/SlashTime/
}}}
