pull into remote git branch fails

[Janne Snabb]

I first thought I encountered bug number 706990 (https://bugs.launchpad.net/bzr-git/+bug/706990) but it looks like that bug should be fixed already in the version that I use. Thus I think this is not a duplicate even though the error message is exactly the same.

How to repeat:

$ bzr branch --bind git://git.verplant.org/collectd.git
Branched 1940 revision(s).
New branch bound to git://git.verplant.org/collectd.git
$ cd collectd.git

The same problem is also confirmed on another server which runs FreeBSD 8.2 i386 and same bzr + bzr-git versions.

Note that this operation doesn't really make sense. If you're going use "bzr pull" you're trying to write to the bound branch (which you don't have write access to).

This happens to me when I use eadd (from the externals plugin) to add external git branch. Just doing bzr branch git://... works fine.

% bzr eadd git://github.com/tpope/vim-surround.git surround
Add external checkout git://github.com/tpope/vim-surround.git surround

This is fixed in bzr-git trunk.
