What is the current best bi-directional git<->bzr method?

What is the current best bi-directional git<->bzr method?

[Alex Bennee]

Hi,

I'm starting to mess around with project on Launchpad which are all
hosted with bzr. Short of convincing these projects to switch DVCS
just for me I need a decent bi-directional way of dealing with bzr
archives.

I found a script[1] which I have hacked a bit[2] to import repo's
fine. However going the other way doesn't seem to work. Before I mess
around too much further I though I'd check if there are any known
working gateways at the moment?

Bidirectional syncing should work, though I've heard there
may be some problems with multiple branches. I had a discussion
with someone about the used mapping, and they hacked up something
in bash, though I've never looked at it. I've lost interest in
git<->bzr syncing (and bzr in general) some time ago, so I never
looked at it further. What specific problem do you have?

It might be that Bazaar changed something in the last year.
They change their repository format and commands quite frequently,
so you might be able to get it to work with an older version.

Erm it spat out a bunch of python errors which didn't make much sense
and I was hoping to avoid digging into:

*** Bazaar has encountered an internal error.
    Please report a bug at https://bugs.launchpad.net/bzr/+filebug
    including this traceback, and a description of what you

*sigh* I suppose it's time to break out those debugging shoes...
