 Frequently ``InternalError`` is raised when there are errors on the OpenSSL
 error stack that were placed there by other libraries that are also using
 OpenSSL. Try removing the other libraries and see if the problem persists.
+If you have no other libraries using OpenSSL in your process, or they do not
+appear to be at fault, it's possible that this is a bug in ``cryptography``.
+Please file an `issue`_ with instructions on how to reproduce it.
