Comment 13 for bug 734145

The good news are, the original bug is probably gone. The bad news... well, see for yourself:

I needed to install the latest trunk of dulwich, because the new bzr-git won't work with dulwich 0.7.0, which is the latest released version. After that, it worked all the way, but crashed at the end with this traceback:

I can assure you that no other bzr was running in that repository at the time. So it's probably bzr-git stepping on its own toes.

Let me know if I can help you investigate that.
