exceptions.KeyError when branching from 1.1 server via bzr+ssh

[Vadim Zeitlin]

I'm using bzr 1.1.0.candidate.1 (latest available package) with Python 2.4 under Debian and 1.3 with Python 2.5 under Windows. I've created a trivial repository for testing:

% mkdir -p ~/src/tst/bzr
% cd $_
% bzr init
% touch foo bar
% bzr add
% bzr ci -m "initial"

and then tried to clone it from Windows:

t:\tmp> bzr branch bzr+ssh://unix-machine-name/home/zeitlin/src/tst/bzr

which resulted in the following error:

Server is too old for fast get_parent_map, reconnecting. (Upgrade the server to Bazaar 1.2 to avoid this)
bzr: ERROR: exceptions.KeyError: 'file:///T:/tmp/bzr/.bzr/repository/upload/ct2djod0w918c9tzkg0x.pack'

I realize that 1.1 is an old version by now but it's still a rather annoying problem for me as I'd prefer to use a packaged version on the Debian system instead of installing latest and greatest from, source if possible. FWIW using bzr: protocol does work but bzr+ssh: would be much more convenient so I'd be grateful for any ideas about how to work around the problem above.

Thanks in advance!
