	if os.path.commonpath((os.path.abspath(full_output_dir), output_dir)) != output_dir:
	return web.Response(status=403)

This code attempts to determine whether the requested file is in the output directory. If not then it returns a 403 error. However, if the requested file is on a different drive to the output dir, then os.commonpath will raise a ValueError, because files on different drives cannot have any common components.

os.commonpath is used in a similar way in various other places.
