nss_wrapper-1.0.3.tar.gz includes this pre-compiled Python object: .ycm_extra_conf.pyc I suppose it was included by mistake (only the source *.py file should have been included). Please consider excluding this file from the upcoming nss_wrapper tarballs.
I looked at 1.1.16 and it doesn't contain any *.pyc files, so I think this can be closed as fixed.
Thanks!
