On windows only, when using this command line:
python post-review --username username --password password
--target-groups=groupname --publish --submit-as=username
--branch="/a/path/name" --revision-range=95695:96202 --summary="Changes to
/a/path/name in 95695:96202 by username" --description-file=svnlogtemp.txt
--repository-url="http://svn.example.com/svnroot/a/path/name"
gives an error when generating the svn diff. The reason is because
post-review is putting a backslash into the url passed to svn.
I have attached a patch that fixes the problem.
