Error using initenv with 0.9.1 on Win32

[alasdair@…]

After building the wiki pages, I get the following error while running initenv in trac-admin (trying to index the repository). This is on a Python 2.3, Win32 install (following the wiki pages on how to install on Windows). This problem disappears if I revert the "Lib\site-packages\trac\versioncontrol" folder back to the files which came with version 0.9b2

I can't reproduce this. What version of the SVN bindings are you using? Also, after the above failure, it should be nevertheless possible to run a trac-admin resync command. Please do that with the log level set to DEBUG. i.e. configure your trac.ini like that:

[logging]
log_file = trac.log
log_level = DEBUG
log_type = stderr

Then, for which changeset does the initial error occur? What is the output of svn log -r XXX -v for that revision?
