exceptions.AttributeError: 'X509' object has no attribute '_subject_invalidator'

[stuertz]

Hi,
I ran into the following traceback using

• windows
• Python 2.7
• Twisted 17.9.0
• pyOpenSSL-17.4.0-py2.7
• OpenSSL 1.0.2m 2 Nov 2017

pyopenssl ist build on my own from setup.py and linked above OpenSSL Version.

Any help would be appreciated.

This is a duplicate of #722 (and fixed when PR #723 merges)

We'll be releasing a version with the fix within the next 24 hours.

Thanks for the report!
