This happens to me with both Ubuntu's python3 deb (version 3.2) and
version 3.3 I compiled from source while trying to sort
[http://bugs.python.org/issue17105 a similar issue out with upstream].
At this point I'm kinda resigned to the conclusion that the 3.x series is
still simply somewhat unstable. As Guido once said in a presentation I
attended "If you get a stacktrace then that's your problem. If you manage
to get python to segfault then that's almost certainly mine."
That said, if someone wants to contact upstream and troubleshoot these
latest python 3.x segfaults then the help would be greatly appreciated!
