Package: python-pyopenssl
Version: 0.6-2
Severity: grave
Tags: patch
Justification: renders package unusable
When I want to create x509 extensions, I get segmentation fault.
The python code which do this is the following:
from OpenSSL import crypto
crypto.X509Extension("basicConstraints", True, "CA:TRUE")
There is a patch on this URL:
http://sourceforge.net/tracker/index.php?func=detail&aid=1166109&group_id=31249&atid=401760
I attached the patch to this email.
This patch is _not_ made by me. I applied this patch to the original package
and it seems to work fine.
