Using bzr-git 0.5.4 and dulwich 0.7.0.

[Jelmer Vernooij (jelmer)]

There is a fix for this in trunk. Alternatively, you can use "bzr branch" rather than "bzr co".

[mathew (meta23)]

Hmm. I tried using trunk, which required that I update bzrlib to version (2,4,0) or higher; so I upgraded bzr to 2.3.1 using the downloads from http://wiki.bazaar.canonical.com/MacOSXDownloads

Now I get a failed import:

 bzr co git://android.git.kernel.org/platform/packages/apps/Launcher2.git launcher2

Looks like that's a dulwich problem?

[Jelmer Vernooij (jelmer)]

You need a newer version of Dulwich (trunk, as well).

[Jelmer Vernooij (jelmer)]

I've updated the metadata so it'll error out if you don't have the right dulwich.

[mathew (meta23)]

Dulwich trunk installed, now I get bzr: ERROR: The remote server unexpectedly closed the connection.
