sre_constants.error: multiple repeat

Beg me pardon. I think you just masked the issue. The real problem is in metadata_extractors.py:

contains_conf_py = len(self.archive.get_files_re(
                r'{0}/conf.py'.format(d), full_path=True))

So you are interpreting directory name as regular expression.

I'm not sure what means 'multiple repeat', but you can demonstrate the problem with:

import re
d="("
re.compile(r'{0}/conf.py'.format(d))

which yields similar error.

and multiple repeat can be reproduced with

d="p++"

I've noticed what is the origin of the problem, there is already a lot of heuristic in sphinx_dir method so I thought it was alright to skip some of the directories if it can't be used as an regex. 49014c298b8a120019f689eaaf is probably better way how to fix the issue.
