lib/utils.py has the following line 168 (beta branch):
yield scm_info.split(path)[-1].lstrip('/'), scm_info
this causes an issue on Windows where the repo name will have a trailing '\' (since that is the path separator on windows)
Replacing with this fixes the problem and everything seems to work for me except statistics (os.kill problem) and repo grouping.
yield scm_info.split(path)[-1].lstrip('/\'), scm_info
