'branch' failed on Windows XP with StopIteration exception

[James P. Gray]

I setup apache web server (version 2.0.55) on my windows machine and 
tried to create a new branch on the same machine by going through the 
web server using the native Windows bzr 0.7 from 
http://bazaar-vcs.org/WindowsDownloads and later from the development 
branch at http://bazaar-ng.org/bzr/bzr.dev/.  The rest of the 
information below relates to the issue with the dev version.  0.7 got a 
different exception.

When I create a branch locally (not though http) things work fine.  
Creating a branch on my Ubuntu system (Dapper flight 5, bzr 0.8pre) also 
works fine branching from the same example branch on windows.  i.e."bzr 
branch http://windowshost/branch test"

I was able to reproduce this using a simple batch script with a few 
commands ("call" is needed to keep from terminating the original when 
calling another batch file):

mkdir tmp
call bzr init tmp
echo x > tmp\a.txt
call bzr add tmp\a.txt
call bzr commit tmp -m "new file"
call bzr branch http://gandalf:5437/tmp x
call bzr branch J:\a\repository\tmp y

I've posted some of the details and created a quick link - 
http://xrl.us/problem
Details include log file for all of the transactions in my test & the 
screen output.

The branch-format 
<http://mysite.verizon.net/vzep3bxh/bzr_problem/branch-format> file 
contains "Bazaar-NG branch, format 6" while the _read_weave_v5 function 
(in traceback below) looks like the handler for format 5.  I didn't see 
a _read_weave_v6 anywhere.  I must be missing something, perhaps I need 
to create a format 5 branch?  If so how? 
<http://mysite.verizon.net/vzep3bxh/bzr_problem/branch-format>

The first branch fails, while the first succeeds.  The last lines of the 
traceback are:

Let me know if there is any additional information that will be of help.

Thanks to everyone who has been working on bzr!
