'Inter1and2Helper' object has no attribute 'source_repo'

bzr branch fails when done inside a shared repository. This is on WinXP, using bzr 2.0.3 or 2.0.4., with bzr commands run under Cygwin. Both bzr installs were done using the "standalone" installer.

Between attempts, I deleted the entire contents of the directory in which the shared repository was made. At first, I was placing the branch directory inside of a directory where a checkout --lightweight had been done, with the checkout directory inside the directory holding the shared repository (as in bug #376931). That is, the command sequence was (showing the actual branches I was fetching so you can try it with the same if you want):

mkdir repo
cd repo
bzr init-repo .
bzr checkout --lightweight lp:~mdipierro/web2py/devel web2py
cd web2py/applications
bzr branch lp:sahana/sahanapy trunk

Two attempts, one each with 2.0.3 and 2.0.4, both crashed with the same error (see below). I was expecting that this might not be legal, so abandoned it.

I then tried making the branch without any checkout directory in the way:

rm -r repo
mkdir repo
cd repo
bzr init-repo .
bzr branch lp:~mdipierro/web2py/devel web2py

After running for over an hour, that hung (i.e. download progress meter stopped), so I ^C'd out. (Had that worked, I would have tried making the other branch within it.) I then the other branch:

rm -r repo
mkdir repo
cd repo
bzr init-repo .
bzr branch lp:sahana/sahanapy trunk

=================================

That crashed with the same error as had the original two attempts. Here is the session, showing the trace, from the final attempt. (Note this is not the same error as was reported in bug #376931.)

There are two other versions of Python in before the version installed with Bazaar, earlier in the path (in the Python26 dir and in /usr/bin -- latter was installed with Cygwin). Bazaar seems to be using its own Python, and in any case, making a branch outside of a shared repository works, as do other bzr commands, so I'm assuming Python versions aren't the problem.

I don't currently have a Linux system to try this on.
