Package: python3-pygit2
Version: 0.22.0-3
Severity: important

Dear Maintainer,

When attempting to import pygit2 in python3 (or python2), I get the 
following error message:

$ python3

Type "help", "copyright", "credits" or "license" for more information.

This was believed fixed in 
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=788095,
but I am able to reproduce it here. I wasn't sure whether it was 
possible/desirable
to reopen an archived bug, so I filed a new one.
