[Upstream] python2.7 crashed with SIGSEGV in IsInMain()

Binary package hint: python2.7

1) lsb_release -rd
Description: Ubuntu 11.04
Release: 11.04

2) apt-cache policy python2.7
python2.7:
  Installed: 2.7.1-5ubuntu2
  Candidate: 2.7.1-5ubuntu2
  Version table:
 *** 2.7.1-5ubuntu2 0
        500 http://us.archive.ubuntu.com/ubuntu/ natty/main i386 Packages
        100 /var/lib/dpkg/status

3) What is (naively) expected to happen is running the attachment at the Terminal:

cd ~/Desktop && wget https://bugs.launchpad.net/ubuntu/+source/libreoffice/+bug/789891/+attachment/2146841/+files/test.py && python test.py

does not segfaults.

4) It segfaults. I do not know the purpose of the file or ramifications of it crashing (valid or deprecated syntax, etc.). Was triaging https://bugs.launchpad.net/ubuntu/+source/openoffice.org/+bug/251427 and trying to reproduce.
