segfault reading isolation_level on closed connection

#74

It happens with version 2.4.2 (from PyPI) on Ubuntu x86_64.

dsn = 'host=127.0.0.1 port=xxxxx user=xxxxxx password=xxxxxx dbname=xxxxxx'
import psycopg2 as pg
print pg.__version__
cnx = pg.connect(dsn=dsn)
cnx.close()
cnx.isolation_level

Output:

  2.4.2 (dt dec pq3 ext)
  Segmentation fault

Seems fixed with the @devel branch.

Yes, but there is still a missing check somewhere: it needs a better message. Thanks for reporting.

Bug fixed, added proper check for connection closed, thank you for the report.

By the way, sorry for having made you wait 10 days: I don't receive email notification for new tickets opened by Lighthouse users, but I receive them from bugs open on the web interface. I've reported the issue one year ago (http://help.lighthouseapp.com/discussions/problems/2122-email-notif...) but it hasn't been fixed yet.
