  I am running an Ubuntu Karmic 9.10 VM instance on Rackspace Cloud.  I
  attempted to install postgresql and psycopg2 and got a stack trace
  towards the end of the process (after "Writing extended state
  information... Done").  I tried to remove the packages (e.g. aptitude
  remove) and then re-install them (e.g. aptitude install) several times
  to reproduce the problem, but had no luck.

  I've attached the console output and the output of valgrind run with
  --leak-check=full
