Can you perhaps try again with trunk ? You should get a different exception now that will help with debugging.

rm -rf BZR-BRANCH/.bzr/repository/git

(* master 49e1d34 Add assertion) seems to still be the same expception though:

Any news on a work-around so we can push our updates to git?

[jugglefish (pniederlag)]

any way we can help to narrow down the problem?

[jugglefish (pniederlag)]

Repo,read_ref is called with 'HEAD' as argument, which in my case is still empty (no commit yet).

weird though this doesn't happen on the very first commit but somewhere in the history. maybe this happens on some brachpoint?

[Jelmer Vernooij (jelmer)]

The _revision_to_objects method is broken and needs a rewrite. There are some corner cases it doesn't handle - including this one.

I haven't had time for this yet.

[narnie (signupnarnie)]

As a point of information, I have no branchpoint in the project this happened on in my case.

[narnie (signupnarnie)]

Due to the slow response of what seems like an important issue, I am abandoning bzr (as has sourceforge.org which hosts my project) as my DVCS. I have spent much time with git over the past several days and am liking how fast and stable it seems to be (and the fact that I can actually push my code to sourceforge.org.).

Another strike for Canonical (I have moved from Ubuntu to Linux Mint Debian Edition tracking testing).

Regretfully,
Narnie

This is also an issue for me too.

I've just noticed git works on windows now, so will be looking at that.

[Michael Gratton (mjog)]

I was having this problem yesterday attempting to dpush to a git repo. I have already worked around it, but on reflection, it may have been caused by any of:

1. Having merged a number of other bzr branches using `bzr join` to the one I was trying to dpush from
2. Creating/moving an empty directory in the bzr repo
3. Some combination of the two - they both happened at the same time that this error started to happen

[Luis Arias (kaaloo)]

I was wondering what kind of workaround you found Mike ? I just ran into this same issue while dpushing one of our bigger bzr repositories to github.
